Failure to comply with these precautions or with specific warnings elsewhere in this manual could result in personal injury or damage to the equipment. The safety precautions listed below represent warnings of certain dangers of which Emerson is aware. You, as the user of the product, should follow these warnings and all other safety precautions necessary for the safe operation of the equipment in your operating environment. Ground the Instrument. To minimize shock hazard, the equipment chassis and enclosure must be connected to an electrical ground. If the equipment is supplied with a three-conductor AC power cable, the power cable must be plugged into an approved three-contact electrical outlet, with the grounding wire (green/yellow) reliably connected to an electrical ground (safety ground) at the power outlet. The power jack and mating plug of the power cable meet International Electrotechnical Commission (IEC) safety standards and local electrical regulatory codes. Do Not Operate in an Explosive Atmosphere. Do not operate the equipment in any explosive atmosphere such as in the presence of flammable gases or fumes. Operation of any electrical equipment in such an environment could result in an explosion and cause injury or damage. Keep Away From Live Circuits Inside the Equipment. Operating personnel must not remove equipment covers. Only Factory Authorized Service Personnel or other qualified service personnel may remove equipment covers for internal subassembly or component replacement or any internal adjustment. Service personnel should not replace components with power cable connected. Under certain conditions, dangerous voltages may exist even with the power cable removed. To avoid injuries, such personnel should always disconnect power and discharge circuits before touching components. Use Caution When Exposing or Handling a CRT. Breakage of a Cathode-Ray Tube (CRT) causes a high-velocity scattering of glass fragments (implosion). To prevent CRT implosion, do not handle the CRT and avoid rough handling or jarring of the equipment. Handling of a CRT should be done only by qualified service personnel using approved safety mask and gloves. Do Not Substitute Parts or Modify Equipment. Do not install substitute parts or perform any unauthorized modification of the equipment. Contact your local Emerson representative for service and repair to ensure that all safety features are maintained. Observe Warnings in Manual.

Note Unless otherwise specified, the designation "MVME5100" refers to all models of the MVME5100-series Single Board Computers. Getting Started The following subsections include information helpful in preparing your equipment. It includes and overview of the MVME5100, any equipment needed to complete the installation, and unpacking instructions. Overview and Equipment Requirements The MVME5100 interfaces to a VMEbus system via its P1 and P2 connectors and contains two IEEE 1386.1 PCI Mezzanine Card (PMC) Slots. The PMC Slots are 64-bit and support both front and rear I/O. Additionally, the MVME5100 is user configurable by setting on-board jumpers. Two I/O modes are possible: PMC mode or SBC mode (also called 761 or IPMC mode). The SBC mode uses the IPMC712 I/O PMC and the MVME712M Transiton Module, or the IPMC761 I/O PMC and the MVME761 Transition Module. The SBC mode is backwards compatible with the MVME761 transition card and the P2 adapter card (excluding PMC I/O routing) used on the MVME2600/2700 product. This mode is accomplished by configuring the on-board jumpers and by attaching an IPMC761 PMC in PMC slot 1. Secondary Ethernet is configured to the rear. PMC mode is backwards compatible with the MVME2300/MVME2400 and is accomplished by simply configuring the on-board jumpers. The following equipment list is appropriate for use in an MVME5100 system: PMCspan PCI expansion mezzanine module (mates with MVME5100) Peripheral Component Interconnect (PCI) Mezzanine Cards (PMCs) (installed on an MVME5100 board) RAM500 memory mezzanine modules (installed on an MVME5100 board) VME system enclosure System console terminal Disk drives (and/or other I/O) and controllers MVME51005E Single Board Computer Installation and Use (6806800A38B) 1 1 Hardware Preparation and Installation Operating system (and/or application software) Unpacking Instructions Avoid touching areas of integrated circuitry; static discharge can damage these circuits. Caution Note If the shipping carton(s) is/are damaged upon receipt, request that the carrier's agent be present during the unpacking and inspection of the equipment. Use ESD Wrist Strap Emerson strongly recommends that you use an antistatic wrist strap and a conductive foam pad when installing or upgrading a system. Electronic components, such as disk drives, computer boards and memory modules, can be extremely sensitive to electrostatic discharge (ESD). After removing the component from its protective wrapper or from the system, place the component on a grounded, static-free, and adequately protected working surface. Do not slide the component over any surface. In the case of a Printed Circuit Board (PCB), place the board with the component side facing up. If an ESD station is not available, you can avoid damage resulting from ESD by wearing an antistatic wrist strap (available locally) that is attached to an active electrical ground. Note 2 A system chassis may not be a suitable grounding source if it is unplugged. MVME51005E Single Board Computer Installation and Use (6806800A38B) 1 Hardware Preparation and Installation Preparation This section includes subsections on hardware configuration that may need to be performed immediately before and after board installation. It includes a brief reminder on setting bits in control registers, setting jumpers for the appropriate configuration, and other VME data considerations. Hardware Configuration To produce the desired board configuration and to ensure proper operation of the MVME5100, it may be necessary to perform certain modifications before and after installation. The following paragraphs discuss the preparation of the MVME5100 hardware components prior to installing them into a chassis and connecting them. A software readable header/ switch register (S1) is available on the MVME5100. This switch is not defined by the hardware and it is shipped in the OFF position, as are all the switches on this board. This S1 switch is available for user-specific configuration needs via the control registers. The MVME5100 provides software control over most of its options by setting bits in control registers. After installing it in a system, you can modify its configuration. For additional information on the board's control registers, refer to the MVME5100 Single Board Computer Programmer's Reference Guide listed in Appendix D, Related Documentation. It is important to note that some options are not software-programmable. These specific options are controlled through manual installation or removal of jumpers, and in some cases, the addition of other interface modules on the MVME5100. The following table lists the manually configured jumpers on the MVME5100, and their default settings. If you are resetting the board jumpers from their default settings, it is important to verify that all settings are reset properly. For example, the SBC mode requires setting jumpers 4, 10 and 17 for rear Ethernet functions, but it also requires resetting jumpers J6 and J20.

Refer to Flash Memory on page 40 for an complete explanation. Jumper Settings Prior to performing the installation instructions, you must ensure that the jumpers are set properly for your particular configuration. For example, if you are using an IPMC761/MVME761 or IPMC712/MVME712 combination in conjunction with the MVME5100, you must reset the jumpers for the SBC mode (jumpers J4, J6, J10, J17 and J20). These are factory configured for the PMC mode. Verify all settings according to the previous table and follow the instructions below if applicable. 4 MVME51005E Single Board Computer Installation and Use (6806800A38B) 1 Hardware Preparation and Installation PMC I/O Mode 2 4 6 SBC I/O Mode J10 2 4 1 3 6 J10 1 3 5 2 4 6 J17 5 2 4 6 1 3 5 J17 1 3 5 J4 J4 123456 7 8 123456 7 8 For rear panel LAN, jumper entire 8 pin header on J4 PMC/SBC (761/IPMC) Mode Selection There are five headers associated with the selection of the PMC or SBC mode: J4, J6 J10, J17 and J20. Three of these headers are responsible for secondary Ethernet I/O (J4, J10 and J17) to either the front panel (PMC mode), or to the P2 connector via J4 (SBC mode). The other two headers (J6 and J20) ensure proper routing of +/- 12V signal routing. The MVME5100 is set at the factory for front panel I/O: PMC mode (see Table 1-1). The SBC mode should only be selected when using one of the IPMC-7xx modules in conjunction with the corresponding MVME7xx transition module. Installation Considerations The MVME5100 draws power from the VMEbus backplane connectors P1 and P2. Connector P2 is also used for the upper 16 bits of data in 32-bit transfers, and for the upper 8 address lines in extended addressing mode. The MVME5100 will not function properly without its main board connected to VMEbus backplane connectors P1 and P2. Whether the MVME5100 operates as a VMEbus master or as a VMEbus slave, it is configured for 32 bits of address and 32 bits of data (A32/D32). However, it handles A16 or A24 devices in the appropriate address ranges. D8 and/or D16 devices in the system must be handled by the processor software. If the MVME5100 tries to access off-board resources in a nonexistent location and if the system does not have a global bus time-out, the MVME5100 waits indefinately for the VMEbus cycle to complete. This will cause the system to lock up. There is only one situation in which the system might lack this global bus time-out; that is when the MVME5100 is not the system controller and there is no global bus time-out elsewhere in the system. Note Software can also disable the bus timer by setting the appropriate bits in the Universe II VMEbus interface. MVME51005E Single Board Computer Installation and Use (6806800A38B) 5 1 Hardware Preparation and Installation Multiple MVME5100 boards may be installed in a single VME chassis; however, each must have a unique VMEbus address. Other MPUs on the VMEbus can interrupt, disable, communicate with, and determine the operational status of the processor(s). Installation This section discusses the installation of PMCs onto the MVME5100, installation of PMCspan modules onto the MVME5100, and the installation of the MVME5100 into a VME chassis. Note If you have ordered one or more of the optional RAM500 memory mezzanine boards for the MVME5100, ensure that they are installed on the board prior to proceeding. If they have not been installed by the factory, and you are installing them yourself, please refer to Chapter 5, RAM500 Memory Expansion Module, for installation instructions.

Remove the filler panel from the VMEbus chassis card slot where you are going to install the MVME5100. If you have installed one or more PMCspan PCI expansion modules onto your MVME5100, you will need to remove filler panels from one additional card slot for each PMCspan, above the card slot for the MVME5100. - If you intend to use the MVME5100 as system controller, it must occupy the left-most card slot (slot 1). The system controller must be in slot 1 to correctly initiate the bus-grant daisy-chain and to ensure proper operation of the IACK daisy-chain driver. MVME51005E Single Board Computer Installation and Use (6806800A38B) 11 1 Hardware Preparation and Installation - If you do not intend to use the MVME5100 as system controller, it can occupy any unused card slot. 4.

It includes necessary information about powering up the system along with the functionality of the switches, status indicators and I/O ports on the front panels of the board. Switches and Indicators The front panel of the MVME5100, as shown in Figure 1-1, incorporates one dual function toggle switch (ABT/RST) and two Light-Emitting Diode (LED) status indicators (BFL, CPU) located on the front panel. ABT/RST Switch The ABT/RST switch operates in the following manner: if pressed for less than 5 seconds, the ABORT function is selected, if pressed for more than 5 seconds, the RESET function is selected. Each function is described below. Abort Function When toggled to ABT, the switch generates an interrupt signal to the processor. The interrupt is normally used to abort program execution and return control to the debugger firmware located in the processor and flash memory. The interrupt signal reaches the processor via ISA bus interrupt line IRQ8. The interrupter connected to the ABORT switch is an edge-sensitive circuit, filtered to remove switch bounce. Reset Function When toggled to RST, the switch resets all onboard devices. To generate a reset, the switch must be depressed for more than five seconds. The on-board Universe ASIC includes both a global and a local reset driver. When the ASIC operates as the System Controller, the reset driver provides a global system reset by asserting the SYSRESET# signal. Additionaly, when the MVME5100 is configured as a System Controller (SCON), a SYSRESET# signal may be generated by toggling the ABT/RST switch to RST, or by a powerup reset, or by a watchdog timeout, or by a control bit in the Miscellaneous Control Register (MISC_CTL) in the Universe ASIC. MVME51005E Single Board Computer Installation and Use (6806800A38B) 13 2 Operation Note SYSRESET# remains asserted for at least 200 ms, as required by the VMEbus specification. Status Indicators There are two Light-Emitting Diode (LED) status indicators located on the MVME5100 front panel. They are labeled BFL and CPU. RST Indicator (DS1) The yellow BFL LED indicates board failure; this indicator is also illuminated during reset as an LED test. The BFL is set if the MODFAIL Register or FUSE Register is set. Refer to the MVME5100 Single Board Computer Programmer's Reference Guide (V5100A/PG) for information on these registers. CPU Indicator (DS2) The green CPU LED indicates CPU activity. Connectors There are three connectors on the front panel of the MVME5100. Two are bottom-labeled 10/100BASE T and one is labeled DEBUG. 10/100BASE T Ports The two RJ-45 ports labeled 10/100BASE T provide the 10BASE T/100BASE TX Ethernet LAN interface. These connectors are top-labeled with the designation LAN1 and LAN2. DEBUG Port The RJ-45 port labeled DEBUG provides an RS232 serial communications interface, based on TL16C550 Universal Asynchronous Receiver/Transmitter (UART) controller chip. It is asynchronous only. For additional information on pin assignments, refer to Chapter 6, Pin Assignments. The DEBUG port may be used for connecting a terminal to the MVME5100 to serve as the firmware console for the factory installed debugger, PPCBug. The port is configured as follows: 8 bits per character 1 stop bit per character Parity disabled (no parity) Baud rate = 9600 baud (default baud rate at power-up) After power-up, the baud rate of the DEBUG port can be reconfigured by using the debugger's Port Format (PF) command. 14 MVME51005E Single Board Computer Installation and Use (6806800A38B) 2 Operation System Powerup After you have verified that all necessary hardware preparation is done, that all connections were made correctly and that the installation is complete, you can power up the system. Initialization Process The MPU, hardware and firmware initialization process is performed by the PPCBug firmware upon system powerup or system reset. The firmware initializes the devices on the MVME5100 in preparation for booting an operating system. The firmware is shipped from the factory with an appropriate set of defaults. Depending on your system and specific application, there may or may not be a need to modify the firmware configuration before you boot the operating system. If it is necessary, refer to Chapter 3, PPCBug Firmware for additional information on modifying firmware default parameters. The following flowchart in Figure 2-1 shows the basic initialization process that takes place during MVME5100 system start-ups. For further information on PPCBug, refer to the following: Chapter 3, PPCBug Firmware Appendix B, Troubleshooting Appendix D, Related Documentation STARTUP INITIALIZATION POST Powerup/reset initialization Initialize devices on the MVME5100 PowerOn Self-Test diagnostics BOOTING Firmware-configured boot mechanism, if so configured.

Boot-Up Sequence MVME51005E Single Board Computer Installation and Use (6806800A38B) 15 3 PPCBug Firmware 3 Introduction The PPCBug firmware is the layer of software just above the hardware. The firmware provides the proper initialization for the devices on the MVME5100 upon powerup or reset. This chapter describes the basics of the PPCBug and its architecture. It also describes the monitor (interactive command portion of the firmware), and provides information on using the PPCBug debugger and the special commands. A complete list of PPCBug commands is also provided. For full user information about PPCBug, refer to the PPCBug Firmware Package User's Manual and the PPCBug Diagnostics Manual, listed in Appendix D, Related Documentation. PPCBug Overview The PPCBug debugger firmware is a powerful evaluation and debugging tool for systems built around Motorola microprocessor. Facilities are available for loading and executing user programs under complete operator control for system evaluation. The PPCBug provides a high degree of functionality, user friendliness, portability and ease of maintenance. The PPCBug also achieves its portability because it was written entirely in the C programming language, except where necessary to use assembler functions. PPCBug includes commands for: Display and modification of memory Breakpoint and tracing capabilities A powerful assembler and disassembler useful for patching programs A self-test at powerup feature which verifies the integrity of the system PPCBug consists of three parts: A command-driven, user-interactive software debugger, described in the PPCBug Firmware Package User's Manual, listed in Appendix D, Related Documentation (hereafter referred to as "debugger" or "PPCBug"). A command-driven diagnostics package for the MVME5100 hardware (hereafter referred to as "diagnostics"). The diagnostics package is described in the PPCBug Diagnostics Manual, listed in Appendix D, Related Documentation. A user interface or debug/diagnostics monitor that accepts commands from the system console terminal. When using PPCBug, you operate out of either the debugger directory or the diagnostic directory. MVME51005E Single Board Computer Installation and Use (6806800A38B) 17 3 PPCBug Firmware If you are in the debugger directory, the debugger prompt PPC6-Bug> is displayed and you have all of the debugger commands at your disposal. If you are in the diagnostic directory, the diagnostic prompt PPC6-Diag> is displayed and you have all of the diagnostic commands at your disposal as well as all of the debugger commands. Because PPCBug is command-driven, it performs its various operations in response to user commands entered at the keyboard. When you enter a command, PPCBug executes the command and the prompt reappears. However, if you enter a command that causes execution of user target code (for example, GO), then control may or may not return to PPCBug, depending on the outcome of the user program. Implementation and Memory Requirements PPCBug is written largely in the C programming language, providing benefits of portability and maintainability. Where necessary, assembly language has been used in the form of separately compiled program modules containing only assembler code. Physically, PPCBug is contained in two socketed 32-pin PLCC Flash devices that together provide 1MB of storage. The executable code is checksummed at every power-on or reset firmware entry. The result (which includes a precalculated checksum contained in the flash devices), is verified against the expected checksum. PPCBug requires a maximum of 768KB of read/write memory. The debugger allocates this space from the top of memory. For example, a system containing 64MB (0x04000000) of read/write memory will place the PPCBug memory locations 0x03F40000 to 0x3FFFFFF. Additionally, the first 1MB of DRAM is reserved for the exception vector table and stack. Using PPCBug PPCBug is command-driven; it performs its various operations in response to commands that you enter at the keyboard. When the PPC6-Bug> prompt appears on the screen, the debugger is ready to accept debugger commands. When the PPC6-Diag> prompt appears on the screen, the debugger is ready to accept diagnostics commands. To switch from one mode to the other, enter SD. What you enter is stored in an internal buffer. Execution begins only after you press the Return or Enter key. This allows you to correct entry errors, if necessary, with the control characters described in the PPCBug Firmware Package User's Manual, listed in Appendix D, Related Documentation. After the debugger executes the command, the prompt reappears. However, depending on what the user program does, if the command causes execution of a user target code (that is, GO), then control may or may not return to the debugger. 18 MVME51005E Single Board Computer Installation and Use (6806800A38B) 3 PPCBug Firmware For example, if a breakpoint has been specified, then control returns to the debugger when the breakpoint is encountered during execution of the user program. Alternately, the user program could return to the debugger by means of the System Call Handler routine RETURN (described in the PPCBug Firmware Package User's Manual). For more about this, refer to the GD, GO and GT command descriptions in the PPCBug Firmware Package User's Manual, listed in Appendix D, Related Documentation . A debugger command is made up of the following parts: The command name, either uppercase or lowercase (for example, MD or md) Any required arguments, as specified by command At least one space before the first argument. Precede all other arguments with either a space or comma. One or more options. Precede an option or a string of options with a semicolon (;). If no option is entered, the command's default option conditions are used. Hardware and Firmware Initialization The debugger performs the hardware and firmware initialization process. This process occurs each time the MVME5100 is reset or powered up. The steps listed below are a high-level outline; be aware that not all of the detailed steps are listed. 1.

Calculates and displays the MPU clock speed, verifies that the MPU clock speed matches the configuration data, and displays a warning message if the verification fails. 28. Displays the BUS clock speed, verifies that the BUS clock speed matches the configuration data,and displays a warning message if the verification fails. 29. Probes PCI bus for supported network devices. 30. Probes PCI bus for supported mass storage devices. 31. Initializes the memory/IO addresses for the supported PCI bus devices. 32. Executes Self-Test, if so configured. (Default is no Self-Test). 33. Extinguishes the board fail LED, if Self-Test passed and outputs any warning messages. 34. Executes boot program, if so configured. (Default is no boot.) 35. Executes the debugger monitor (that is, issues the PPC6-Bug> prompt). Default Settings The following sections provide information pertaining to the firmware settings of the MVME5100. Default (factory set) Environment (ENV) commands are provided to inform you on how the MVME5100 was configured at the time it left the factory. CNFG - Configure Board Information Block Use this command to display and configure the Board Information Block, which is resident within the NVRAM. This data block contains various elements detailing specific operational parameters of the MVME5100. The structure for the board is shown in the following example: 20 Board (PWA) Serial Number = MOT00xxxxxxx Board Identifier = MVME5100 Artwork (PWA) Identifier = 01-W3518FxxB MPU Clock Speed = 450 Bus Clock Speed = 100 MVME51005E Single Board Computer Installation and Use (6806800A38B) 3 PPCBug Firmware Ethernet Address = 0001AF2A0A57 Primary SCSI Identifier = 07 System Serial Number = nnnnnnnn System Identifier = Emerson MVME5100 License Identifier = nnnnnnnn The Board Information Block parameters shown above are left-justified character (ASCII) strings padded with space characters. The Board Information Block is factory-configured before shipment. There is no need to modify block parameters unless the NVRAM is corrupted. Refer to the PPCBug Firmware Package User's Manual, listed in Appendix D, Related Documentation for a description of CNFG and examples. ENV - Set Environment Use the ENV command to view and/or configure interactively all PPCBug operational parameters that are kept in Non-Volatile RAM (NVRAM). Refer to the PPCBug Firmware Package User's Manual for a description of the use of ENV. Additional information on registers in the Universe ASIC that affect these parameters is contained in your MVME5100 Programmer's Reference Guide, listed in Appendix D, Related Documentation. Listed and described below are the parameters that you can configure using ENV. The default values shown were those in effect when this publication went to print. Configuring the PPCBug Parameters The parameters that can be configured using ENV are: Bug or System environment [B/S] = B? B Bug is the mode where no system type of support is displayed. However, system-related items are still available. (Default) S System is the standard mode of operation, and is the default mode if NVRAM should fail. System mode is defined in the PPCBug Firmware Package User's Manual listed in Appendix D, Related Documentation. Maximum Memory Usage (MB,0=AUTO) = 1? This parameter specifies the maximum number of megabytes the bug is allowed to use. Allocation begins at the top of physical memory and expands downward as more memory is required until the maximum value is reached. MVME51005E Single Board Computer Installation and Use (6806800A38B) 21 3 PPCBug Firmware If a value of zero is specified, memory will continue to be increased as needed until half of the available memory is consumed (that is, 32MB in a 64MB system). This mode is useful for determining the full memory required for a specific configuration. Once this is determined, a hard value may be given to the parameter and it is guaranteed that no memory will be used over this amount. The default value for this parameter is one. Note The bug does not automatically acquire all of the memory it is allowed. It accumulates memory as necessary in one megabyte blocks. Field Service Menu Enable [Y/N] = N?

The MVME5100 is a high-performance product featuring PowerPlus II architecture with a choice of PowerPC processors--either the MPC7410 with AltiVecTM technology for algorithmic intensive computations or the low-power MPC750. The MVME5100 incorporates a highly optimized PCI interface and memory controller enabling up to 582MB memory read bandwidth and 640MB burst write bandwidth. The optimization of the memory bus is as important as optimization of the system bus in order to achieve maximum system performance. The MVME5100's advanced PowerPlus II Architecture supports full PCI throughput of 264MB without starving the CPU of its memory. Additional features of the MVME5100 include dual Ethernet ports, dual serial ports and up to 17MB of Flash. Features Summary The table below lists the general features for the MVME5100. Refer to Appendix A, Specifications, for additional product specifications and information. Table 4-1.

The board can be equipped with either the MPC7410 processor with AltiVecTM technology for algorithmic intensive computations or with the low-power MPC750 for low-power or field applications. Designed to meet the needs of OEMs servicing the military and aerospace, industrial automation and semiconductor process equipment market segments, the MVME5100 is available in both commercial grade (0 to 55 C) and industrial grade (-20 to 71 C) temperatures. The MVME5100 has two Input/Output (I/O) modes of operation: PMC and SBC (also called 761 mode or IPMC mode). In PMC mode, it is fully backwards compatible with previous generation dual PMC products such as the MVME2300 and MVME2400. In the SBC mode, the MVME5100 is backwards compatible with the corresponding Emerson MVME712 or MVME761 transition board originated for use with previous generation singleboard computer products, such as the MVME2600 and MVME2700. It is important to note that MVME712 and MVME761 compatibility is accomplished with the addition of the corresponding IPMC712 or IPMC761 (an optional add-on PMC card). The IPMC712 and IPMC761 provides rear I/O support for one single-ended ultra-wide SCSI device, one parallel port, four serial ports (two synchronous for 761 and one for 712, and two asynchronous/synchronous for 761 and three for 712) and I2C functionality through the Hawk ASIC.

MVME5100 Block Diagram Processor The MVME5100 incorporates a BGA foot print that supports both the MCP7410 and the MCP75x processors. The maximum external processor bus speed is 100 MHz. Note The MCP7410 is configured to operate only with the PowerPC 60xbus interface. MVME51005E Single Board Computer Installation and Use (6806800A38B) 39 4 Functional Description System Memory Controller and PCI Host Bridge The on-board Hawk ASIC provides the bridge function between the processor's bus and the PCI bus. It provides 32-bit addressing and 64-bit data; however, 64-bit addressing (dual address cycle) is not supported. The ASIC also supports various processor external bus frequencies up to 100 MHz. There are four programmable map decoders for each direction to provide flexible address mappings between the processor and the PCI bus. The ASIC also provides an Multi-Processor Interrupt Controller (MPIC) to handle various interrupt sources. They are: four MPIC timer interrupts, interrupts from all PCI devices and two software interrupts. Memory The following subsections describe various memory capabilities on the MVME5100 including Flash memory and ECC SDRAM memory. Flash Memory The MVME5100 contains two banks of Flash memory. Bank B consists of two 32-pin devices which can be populated with 1MB of Flash memory (only 8-bit writes are supported for this bank). Refer to the application note following for more write-protect information on this product. Bank A has 4 16-bit Smart Voltage FLASH SMT devices. With 32Mbit flash devices, the flash memory size is 16MB. Note that only 32-bit writes are supported for this bank of flash memory. Application Note: For Am29DL322C or Am29DL323C, 32Megabit (4M x 8-Bit/2M x 16-bit) CMOS 3.0 Volt-only Flash Memory. The Write Protect function provides a hardware method of protecting certain boot sectors. If the system asserts V IL (low signal) on the WP#/ACC pin, the device disables the program and erase capability, independently of whether those sectors were protected or unprotected using the method described in the Sector/Sector Block Protection and Unprotection of the AMD datasheet. The two outermost 8Kbyte boot sectors are the two sectors containing the lowest addresses in a bottom-boot-configured device, or the two sectors containing the highest addresses in a top-boot-configured device. The aforementioned implemented device (at the time of this printing is the only qualified Flash device used on this product) is a top-boot device, and as such, the write protected area is in the upper 16KB of each device. Since it uses 4 devices for the soldered Flash bank, the write protected region corresponds to the upper 64KB of the soldered Flash memory map. Thus the address range of $F4FF 0000 to F4FF FFFF is the write protected region when the J16 header is jumpered across pins 2 and 3. If PPCBug tries to write to those write-protected address areas when pins 2-3 on J16 are set, the command will simply not finish (i.e., erase sector function stops at $F4FF 0000). 40 MVME51005E Single Board Computer Installation and Use (6806800A38B) 4 Functional Description ECC SDRAM Memory The MVME5100's on-board memory and optional memory mezzanines allow for a variety of memory size options. Memory size can be 64 or 512MB for a total of 1.5GB on-board and mezzanine ECC memory. The memory is controlled by the hardware which provides single-bit error correction and double-bit error detection (ECC is calculated over 72-bits). Either 1 or 2 mezzanines can be installed. Each mezzanine will add 1 bank of SDRAM memory of 256 or 512MB. A total of 1GB of mezzanine memory can be added. Refer to Chapter 5, RAM500 Memory Expansion Module for more information. P2 Input/Output (I/O) Modes The MVME5100 has two P2 I/O modes (SBC and PMC) that are user- configurable with jumpers on the board (J6 and J20). The jumpers route the on-board Ethernet port 2 to row C of the P2 connector. Ethernet jumpers (J4, J10, and J17) should also be configured. The SBC mode (also called 761 or IPMC mode) are backwards compatible with the corresponding MVME712 and MVME761 transition cards and the P2 adapter card (excluding PMC I/O routing) used on the MVME2600/2700. The SBC mode is accomplished by configuring the on-board jumpers and attaching an IPMC712 or IPMC761 PMC in PMC slot 1 of the MVME5100. PMC mode is backwards compatible with the MVME2300/MVME2400. PMC mode is accomplished by simply configuring the on-board jumpers. Note Refer to Chapter 6, Pin Assignments for P2 Input/Output Mode jumper settings. Input/Output Interfaces The following subsections describe the major I/O interfaces on the MVME5100 including Ethernet, VMEbus, asynchronous communications ports, real-time clock/NVRAM/Watchdog Timer, other timer interfaces, interrupt routing capabilities and IDSEL routing capabilities. Ethernet Interface The MVME5100 incorporates dual Ethernet interfaces (Port 1 and Port 2) via two Fast Ethernet PCI controller chips. The Port 1 10BaseT/100BaseTX interface is routed to the front panel. The Port 2 Ethernet interface is routed to either the front panel or the P2 connector as configured by jumpers. The front panel connectors are of the RJ45 type. Every board is assigned two Ethernet Station Addresses. The address is $0001AFXXXXX where XXXXX is the unique number assigned to each interface. Each Ethernet Station Address is displayed on a label attached to the PMC front-panel keep-out area. In addition, LAN 1 Ethernet address is stored in the configuration area of the NVRAM specified by the Boot ROM and in SROM. MVME51005E Single Board Computer Installation and Use (6806800A38B) 41 4 Functional Description VMEbus Interface The VMEbus interface is provided by the Universe II ASIC. Refer to the Universe II User's Manual, as listed in Appendix D, Related Documentation, for additional information. Asynchronous Communications The MVME5100 provides dual asynchronous debug ports. The serial signals COM1 and COM2 are routed through appropriate EIA-232 drivers and receivers to an RJ45 connector on the front panel (COM1) and an on-board connector (COM2). The external signals are ESD protected. Real-Time Clock & NVRAM & Watchdog Timer The MVME5100's design incorporates 32KB of non-volatile static RAM, along with a real-time clock and a watchdog function an integrated device. Refer to the M48T37V CMOS 32Kx8 Timekeeper SRAM Data Sheet, as referenced in Appendix D, Related Documentation for additional programming and engineering information. Timers Timers and counters on the MVME5100 are provided by the board's hardware (Hawk ASIC). There are four 32-bit timers on the board that may be used for system timing or to generate periodic interrupts. Interrupt Routing Legacy interrupt assignment for the PCI/ISA Bridge is maintained to ensure software compatibility between the MVME5100 and the MVME2700 while in SBC mode. This is accomplished by using the corresponding on-board IPMC712 or IPMC761 connector to route the PCI/ISA Bridge interrupt signal to the external interrupt 0 of the Hawk ASIC (MPIC). Note The SCSI device on either the IPMC712 or IPMC761 uses the standard INTA# pin J1104 of PMC Slot 1. IDSEL Routing Legacy IDSEL assignment for the PCI/ISA Bridge is also maintained to ensure software compatibility between MVME5100 and the MVME2700 while in SBC mode (also called 761 or IPMC mode). This is accomplished by using either the on-board IPMC712 or IPMC761 connector to route IDSEL (AD11) to the PCI/ISA Bridge on the IPMC712 or IPMC761. Note The SCSI device on the IPMC712 and IPMC761 uses the standard IDSEL pin J12-25 connected to AD16. When a standard PMC card (not the IPMC712 or IPMC761) is plugged into slot 1, its IDSEL assignment corresponds to the standard IDSEL pin J12-25 and shall be connected to AD16. 42 MVME51005E Single Board Computer Installation and Use (6806800A38B) 5 RAM500 Memory Expansion Module 5 Overview The RAM500 memory expansion module can be used on the MVME5100 as an option for additional memory capability. Each expansion module is a single bank of SDRAM with either 256 or 512MB of available ECC memory. Currently, two expansion modules can be used in tandum to produce an additional expanded memory capability of 1GB. There are two configurations of the board to accommodate tandum usage. The bottom expansion module has both a bottom and top connector: one to plug into the base board, and one to mate with the second RAM500 module. The top expansion module is designed with just a bottom connector to plug into the lower RAM500 module. The RAM500 incorporates a Serial ROM for system memory Serial Presence Detect (SPD) data. A maximum of two expansion modules are allowed: one bottom and one top. If only one module is used, the RAM500 module with the top configuration is recommended. Features The following table lists the features of the RAM500 memory expansion module: Table 5-1. RAM500 Feature Summary Form Factor Dual sided mezzanine, with screw/post attachment to host board SROM Single 256x8 I2C SROM for Serial Presence Detect Data SDRAM Double-Bit-Error detect, Single-Bit-Error correct across 72 bits 128, 256, or 512MB mezzanine memory @ 100MHz Memory Expansion Flexibility Any RAM500 memory size can be attached to the host board followed by any secondary RAM500 memory size for maximum memory expansion flexibility. Functional Description The following sections describe the physical and electrical structure of the RAM500 memory expansion module. MVME51005E Single Board Computer Installation and Use (6806800A38B) 43 5 RAM500 Memory Expansion Module RAM500 Description The RAM500 is a memory expansion module that is used on the MVME5100 Single Board Computer. The RAM500 is based on a single memory mezzanine board design with the flexibility of being populated with different sized SDRAM components and SPD options to provide a variety of memory configurations. The design of the RAM500 allows any memory size module to connect to and operate with any other available memory size module. The optional RAM500 memory expansion module is currently available in three sizes: 128MB, 256MB, and 512MB, with a total added capacity of 1GB. The SDRAM memory is controlled by the Hawk ASIC, which provides single-bit error correction and double-bit error detection. ECC is calculated over 72-bits. Refer to the MVME5100 Single Board Computer Programmer's Reference Guide (V5100A/PG) for more information. The RAM500 consists of a single bank/block of memory. The memory block size is dependent upon the SDRAM devices installed. Refer to Table 5-2 for memory options. The RAM500 memory expansion module is connected to the host board with a 140-pin AMP 0.6mm Free Height plug connector. If the expansion module is designed to accommodate another RAM500 module, the bottom expansion module will have two 140-pin AMP connectors installed: one on the bottom side of the module, and one on the top side of the module. The RAM500 memory expansion module draws +3.3V through this connector. When populated, the optional RAM500 memory expansion memory blocks should appear as Block C and Block E to the Hawk ASIC. Block C and E are used because each of the module's SPD is defined to correspond to two banks of memory each: C and D for the first SPD and E and F for the second SPD. The RAM500 SPD uses the SPD JEDEC standard definition and is accessed at address $AA or $AC. Refer to the following section on SROM for more details. Table 5-2.

Figure 5-1. RAM500 Block Diagram SROM The RAM500 memory expansion module contains a single 3.3V, 256 x 8, Serial EEPROM device (AT24C02). The Serial EEPROM provides Serial Presence Detect (SPD) storage of the module memory subsystem configuration. The RAM500 SPD is software addressable by a unique address as follows: The first RAM500 attached to the host board has its SPD addressable at $AA. The second RAM500 attached to the host board has its SPD addressable at $AC. This dynamic address relocation of the RAM500 SPD shall be done using the bottomside connector signal A1_SPD and A0_SPD. MVME51005E Single Board Computer Installation and Use (6806800A38B) 45 5 RAM500 Memory Expansion Module Host Clock Logic The host board provides four SDRAM clocks to the memory expansion connector. The frequency of the RAM500 CLKS is the same as the host board. RAM500 Module Installation One or more RAM500 memory expansion modules can be mounted on top of the MVME5100 for additional memory capacity. To upgrade or install a RAM500 module, refer to Figure 5-2 and proceed as follows: 1. Attach an ESD strap to your wrist. Attach the other end of the ESD strap to the chassis as a ground. The ESD strap must be secured to your wrist and to ground throughout the procedure. 2. Perform an operating system shutdown. Turn the AC or DC power off and remove the AC cord or DC power lines from the system. Remove the chassis or system cover(s) as necessary for access to the CompactPCI boards. 3. Carefully remove the MVME5100 from its VME card slot and lay it flat, with connectors P1 and P2 facing you. 4. Inspect the RAM500 module that is being installed on the MVME5100 host board (bottom configuration if two are being installed, top configuration if only one is being installed) to ensure that standoffs are installed in the three mounting holes on the module. 5. With standoffs installed in the three mounting holes on the RAM500 module, align the standoffs and the P1 connector on the module with the three holes and the J16 connector on the MVME5100 host board and press the two connectors together until they are firmly seated in place. Figure 5-2. RAM500 Module Placement on MVME5100 46 MVME51005E Single Board Computer Installation and Use (6806800A38B) 5 RAM500 Memory Expansion Module 6. (Optional step) If a second RAM500 module is being used, align the top connector on the bottom RAM500 module with the bottom connector on the top RAM500 module and press the two connectors together until the connectors are seated in place. 7. Insert the three short Phillips screws through the holes at the corners of the RAM500 and screw them into the standoffs. 8. Turn the entire assembly over, and fasten the three nuts provided to the standoff posts on the bottom of the MVME5100 host board. 9. Reinstall the MVME5100 assembly in its proper card slot. Be sure the host board is well seated in the backplane connectors. Do not damage or bend connector pins. 10. Replace the chassis or system cover(s), reconnect the system to the AC or DC power source, and turn the equipment power on. RAM500 Connectors RAM500 memory expansion modules are populated with one or two connectors. If the module is to be used in tandum with a second RAM500 module, the "bottom" module will have two connectors: one to mate with the MVME5100 host board (P1), and one to mate with the "top" RAM500 module (J1). The "top" RAM500 module has only one connector, since it needs to mate only with the RAM500 module directly underneath it and because an added connector on a tandum RAM500 configuration would exceed the height limitations in some backplanes. If only one RAM500 module is being used, a top module, single connector configuration is used. A 4H plug and receptacle are used on both boards to provide a 4 millimeter stacking height between dual RAM500 cards and the host board. The following subsections specify the pin assignments for the connectors on the RAM500. Bottom Side Memory Expansion Connector (P1) The bottom side connector on the RAM500 is a 140-pin AMP 0.6mm Free Height mating plug. This plug includes common ground contacts that mate with standard AMP receptacle assemblies or AMP GIGA assemblies with ground plates. A single memory expansion module will have 1 bank of SDRAM for a maximum of 5Mbytes of memory. Attaching a second memory module to the first module will provide 2 banks of SDRAM with a maximum of 1Gigabytes. Table 5-3.

RAM500 Programming Issues The RAM500 contains no user programmable registers, other than the Serial Presence Detect (SPD) Data. Serial Presence Detect (SPD) Data This register is partially described for the RAM500 within the MVME5100 Single Board Computer Programmer's Reference Guide. The register is accessed through the I2C interface of the Hawk ASIC on the host board (MVME5100). The RAM500 SPD is software addressable by a unique address as follows: The first RAM500 attached to the host board has has an SPD address of $AA. The second RAM500 attached to the top of the first RAM500 has an SPD address of $AC. 52 MVME51005E Single Board Computer Installation and Use (6806800A38B) 6 Pin Assignments 6 Introduction This chapter provides information on pin assignments for various jumpers and connectors on the MVME5100 Single Board Computer.

The pin assignments for the connector are specified by the IEEE P1014-1987 VMEbus Specification and the VME64 Extension Standard. Row B of connector P2 provides power to the MVME5100 and to the upper 8 VMEbus address lines and additional 16 VMEbus data lines. Rows A, C, Z and D provide power and interface signals to the MVME712 or MVME761 transition module in SBC mode (also called 761 mode and IPMC mode). It is important to note that the PMC I/O routing to row D and Z are not the same as MVME2600/2700. The PMC I/O routing for row D and row Z is the same as the PMC mode with the exception of pins Z1, 3, 5, 7, 9, 11, 13, 15 and 17 which are used for extended SCSI. Note A PMC card installed in slot 2 of an MVME5100 in SBC mode MUST NOT connect to J24-2, 5, 8, 11, 14, 17, 20, 23 and 26 since they are connected to the extended SCSI signals of the MVME5100.

This includes a description of memory maps, control and status registers, PCI arbitration, interrupt handling, sources of reset and big/little-endian issues. For additional programming information about the MVME5100, refer to the MVME5100-Series Single Board Computer Programmer's Reference Guide, listed in Appendix D, Related Documentation . For programming information about the PMCs, refer to the applicable user's manual furnished with the PMCs. Memory Maps There are multiple buses on the MVME5100 and each bus domain has its own view of the memory map. The following sections describe the MVME5100 memory organization from the following three points of view: The mapping of all resources as viewed by the MPU (processor bus memory map) The mapping of onboard resources as viewed by PCI local bus masters (PCI bus memory map) The mapping of onboard resources as viewed by VMEbus masters (VMEbus memory map) Additional, more detailed memory maps can be found in the MVME5100-Series Single Board Computer Programmer's Reference Guide, listed in Appendix D, Related Documentation. Processor Bus Memory Map The processor memory map configuration is under the control of the PHB and SMC portions of the Hawk ASIC. The Hawk adjusts system mapping to suit a given application via programmable map decoder registers. At system power-up or reset, a default processor memory map takes over. MVME51005E Single Board Computer Installation and Use (6806800A38B) 73 7 Programming the MVME5100 Default Processor Memory Map The default processor memory map that is valid at power-up or reset remains in effect until reprogrammed for specific applications. Table 7-1 defines the entire default map ($00000000 to $FFFFFFFF). Table 7-1.

If the rom_b_rv control bit is set, this address range maps to ROM/FLASH Bank B (socketed 1MB Flash). For an example of the CHRP memory map, refer to the following table. For detailed processor memory maps, including suggested CHRP- and PREP-compatible memory maps, refer to the MVME5100-Series Single Board Computer Programmer's Reference Guide. 74 MVME51005E Single Board Computer Installation and Use (6806800A38B) 7 Programming the MVME5100 Processor Memory Map The following table describes a suggested CHRP Memory Map from the point of view of the processor. This memory map is an alternative to the PREP memory map. Note: in all recommended CHRP maps, the beginning of PCI Memory Space is determined by the end of DRAM rounded up to the nearest 256MB-boundry as required by CHRP. For example, if memory was 1G on the baseboard and 192MB on a mezzanine, the beginning of PCI memory would be rounded up to address 0x50000000 (1G + 256M). Table 7-2.

The first 1MB of ROM/FLASH Bank A appears at this range after a reset if the rom_b_rv control bit is cleared. If the rom_b_rv control bit is set, this address maps to ROM/FLASH Bank B. MVME51005E Single Board Computer Installation and Use (6806800A38B) 75 7 Programming the MVME5100 4. The only method to generate a PCI Interrupt Acknowledge cycle (8259 IACK) is to perform a read access to the Hawks PIACK Register at 0xFEFF0030. 5. VME should be placed at the top of PCI memory space. The following table shows the programmed values for the associated Hawk PCI Host Bridge Registers for the suggested Processor Memory Map.

The MVME5100 is fully capable of supporting both PREP and CHRP PCI Memory Maps with RAM size limited to 2GB. VME Memory Map The MVME5100 is fully capable of supporting both the PREP and the CHRP VME Memory Maps examples with RAM size limited to 2GB. PCI Local Bus Memory Map The PCI memory map is controlled by the MPU/PCI bus bridge controller portion of the Hawk ASIC and by the Universe PCI/VME bus bridge ASIC. The Hawk and Universe devices adjust system mapping to suit a given application via programmable map decoder registers. No default PCI memory map exists. Resetting the system turns the PCI map decoders off, and they must be reprogrammed in software for the intended application. For detailed PCI memory maps, including suggested CHRP- and PREP-compatible memory maps, refer to the MVME5100-Series Single Board Computer Programmer's Reference Guide. VMEbus Memory Map The VMEbus is programmable. Like other parts of the MVME5100 memory map, the mapping of local resources as viewed by VMEbus masters varies among applications. 76 MVME51005E Single Board Computer Installation and Use (6806800A38B) 7 Programming the MVME5100 The Universe PCI/VME bus bridge ASIC includes a user-programmable map decoder for the VMEbus-to-local-bus interface. The address translation capabilities of the Universe enable the processor to access any range of addresses on the VMEbus. Recommendations for VMEbus mapping, including suggested CHRP- and PREP-compatible memory maps, can be found in the MVME5100-Series Single Board Computer Programmer's Reference Guide. Figure 7-1 shows the overall mapping approach from the standpoint of a VMEbus master. Programming Considerations Good programming practice dictates that only one MPU at a time have control of the MVME5100 control registers. Of particular note are: Registers that modify the address map Registers that require two cycles to access VMEbus interrupt request registers PCI Arbitration There are seven potential PCI bus masters on the MVME5100: Hawk ASIC (MPU/PCI bus bridge controller) Winbond W83C554 PIB (PCI/ISA bus bridge controller) DECchip 21143 Ethernet controller Universe II ASIC (PCI/VME bus bridge controller) PMC Slot 1 (PCI mezzanine card) PMC Slot 2 (PCI mezzanine card) PCI Expansion Slot The Winbond W83C554 PIB device supplies the PCI arbitration support for these seven types of devices. The PIB supports flexible arbitration modes of fixed priority, rotating priority and mixed priority, as appropriate in a given application. Details on PCI arbitration can be found in the MVME5100-Series Single Board Computer Programmer's Reference Guide.

Sources of interrupts may be any of the following: The Hawk ASIC itself (timer interrupts, transfer error interrupts or memory error interrupts) The processor (processor self-interrupts) The PCI bus (interrupts from PCI devices) The ISA bus (interrupts from ISA devices) Figure 7-2 illustrates interrupt architecture on the MVME5100.

They are not functional on the MVME5100. Sources of Reset The MVME5100 has nine potential sources of reset: 1. Power-on reset 2. RST switch (resets the VMEbus when the MVME5100 is system controller) 3. Watchdog timer Reset function controlled by the SGS-Thomson MK48T559 timekeeper device (resets the VMEbus when the MVME5100 is system controller) 4. ALT_RST function controlled by the Port 92 register in the PIB (resets the VMEbus when the MVME5100 is system controller) 5. PCI/ISA I/O Reset function controlled by the Clock Divisor register in the PIB 6. The VMEbus SYSRESET signal 7. VMEbus Reset sources from the Universe ASIC (PCI/VME bus bridge controller): the System Software reset, Local Software Reset and VME CSR Reset functions. Note On the MVME5100, Watchdog Timer 2 is a source of reset only if component R206 is installed on the board. Table 7-5 shows which devices are affected by the various types of resets.

The PowerPC processor and the VMEbus are inherently big-endian, while the PCI bus is inherently little-endian. The following sections summarize how the MVME5100 handles software and hardware differences in big- and little-endian operations. For further details on endian considerations, refer to the MVME5100-Series Single Board Computer Programmer's Reference Guide. Processor/Memory Domain The MPC750 processor can operate in both big-endian and little-endian mode. However, it always treats the external processor/memory bus as big-endian by performing address rearrangement and reordering when running in little-endian mode. The MPC registers in the Hawk MPU/PCI bus bridge controller, SMC memory controller, as well as DRAM, Flash and system registers, always appear as big-endian. Role of the Hawk ASIC Because the PCI bus is little-endian, the PHB portion of the Hawk performs byte swapping in both directions (from PCI to memory and from the processor to PCI) to maintain address invariance while programmed to operate in big-endian mode with the processor and the memory subsystem. In little-endian mode, the PHB reverse-rearranges the address for PCI-bound accesses and rearranges the address for memory-bound accesses (from PCI). In this case, no byte swapping is done. MVME51005E Single Board Computer Installation and Use (6806800A38B) 81 7 Programming the MVME5100 PCI Domain The PCI bus is inherently little-endian. All devices connected directly to the PCI bus operate in little-endian mode, regardless of the mode of operation in the processor's domain. PCI and Ethernet Ethernet is byte-stream-oriented; the byte having the lowest address in memory is the first one to be transferred regardless of the endian mode. Since the PHB maintains address invariance in both little-endian and big-endian mode, no endian issues should arise for Ethernet data. Bigendian software must still take the byte-swapping effect into account when accessing the registers of the PCI/Ethernet device, however. Role of the Universe ASIC Because the PCI bus is little-endian while the VMEbus is big-endian, the Universe PCI/VME bus bridge ASIC performs byte swapping in both directions (from PCI to VMEbus and from VMEbus to PCI) to maintain address invariance, regardless of the mode of operation in the processor's domain. VMEbus Domain The VMEbus is inherently big-endian. All devices connected directly to the VMEbus must operate in big-endian mode, regardless of the mode of operation in the processor's domain. In big-endian mode, byte-swapping is performed first by the Universe ASIC and then by the PHB. The result is transparent to big-endian software (a desirable effect). In little-endian mode, however, software must take the byte-swapping effect of the Universe ASIC and the address reverse-rearranging effect of the PHB into account. For further details on endian considerations, refer to the MVME5100-Series Single Board Computer Programmer's Reference Guide. 82 MVME51005E Single Board Computer Installation and Use (6806800A38B) A Specifications A This appendix lists general specifications and power characteristics for the MVME5100 Single Board Computer. It also provides information on cooling requirements. A complete functional description of the MVME5100 Single Board Computer appears in Chapter 4, Functional Description.

Note The power requirements for the MVME5100 include the power requirements for a PMC or IMPC Modules. The PMC specification allows for 7.5 watts per PMC slot. The 15 watts total can be drawn from any combination of the three voltage sources provided by the MVME5100: +5V, +12V and -12V. Cooling Requirements Refer to Appendix C, Thermal Analysis for more information. EMC Compliance The MVME5100 was tested in an EMC-compliant chassis and meets the requirements for EN55022 Class B equipment. Compliance was achieved under the following conditions: Shielded cables on all external I/O ports Cable shields connected to earth ground via metal shell connectors bonded to a conductive module front panel Conductive chassis rails connected to earth ground. This provides the path for connecting shields to earth ground. Front panel screws properly tightened. For minimum RF emissions, it is essential that the conditions above be implemented. Failure to do so could compromise the EMC compliance of the equipment containing the module. 84 MVME51005E Single Board Computer Installation and Use (6806800A38B) B Troubleshooting B Solving Startup Problems In the event of difficulty with your MVME5100, perform the simple troubleshooting steps listed in the table below before calling for help or sending the board back for repair.

TROUBLESHOOTING PROCEDURE COMPLETE 88 MVME51005E Single Board Computer Installation and Use (6806800A38B) C Thermal Analysis C Ambient temperature, air flow, board electrical operation and software operation affect board component temperatures. To evaluate the thermal performance of a circuit board assembly, you should test the board under actual operating conditions. These operating conditions vary depending on system design. A thermal analysis was performed in a representative system to verify operation within specified ranges. Refer to Table A-1 in Appendix A, Specifications. You should evaluate the thermal performance of the board in your application. This appendix gives systems integrators the information necessary to conduct thermal evaluations of the board in their specific system configuration. It identifies thermally significant components and lists the corresponding maximum allowable component operating temperatures. It also provides example procedures for component-level temperature measurements. Thermally Significant Components Table C-1 summarizes components that show significant temperature rises. You should monitor these components to assess thermal performance. Table C-1 also supplies the component reference designator and the maximum allowable operating temperature. You can find components on the board by their reference designators. Refer to Figure C-1 and Figure C-2. The preferred temperature measurement location for a component may be: junction - refers to the temperature measured by an on-chip thermal device case - refers to the temperature at the top, center surface of the component MVME51005E Single Board Computer Installation and Use (6806800A38B) 89 C Thermal Analysis air - refers to the ambient temperature near the component Table C-1.

Thermally Significant Components on the IPMC761 Module - Primary Side Component Temperature Measurement This section outlines general temperature measurement methods. For the specific types of measurements required for thermal evaluation of this board, see Table C-1. Preparation We recommend 40-gage thermocouples for all thermal measurements. Larger gage thermocouples can wick heat away from the components and disturb air flowing past the board. 92 MVME51005E Single Board Computer Installation and Use (6806800A38B) C Thermal Analysis Allow the board to reach thermal equilibrium before taking measurements. Most circuit boards reach thermal equilibrium within 30 minutes. After the warm up period, monitor a small number of components over time to assure that equilibrium is reached. Measuring Junction Temperature Some components have an on-chip thermal measuring device such as a thermal diode. For instructions on measuring temperatures using the on-board device, refer to the MVME5100 component manufacturer's documentation listed in Appendix D, Related Documentation. Measuring Case Temperature Measure the case temperature at the center of the top of the component. Make sure there is good thermal contact between the thermocouple junction and the component. We recommend you use a thermally conductive adhesive such as Loctite 384. If components are covered by mechanical parts such as heatsinks, you need to machine these parts to route the thermocouple wire. Make sure that the thermocouple junction contacts only the electrical component. Also make sure that heatsinks lay flat on electrical components. Figure C-3 shows one method of machining a heatsink base to provide a thermocouple routing path. Note Machining a heatsink base reduces the contact area between the heatsink and the electrical component. You can partially compensate for this effect by filling the machined areas with thermal grease. The grease should not contact the thermocouple junction.

Mounting a Thermocouple Under a Heatsink Measuring Local Air Temperature Measure local component ambient temperature by placing the thermocouple downstream of the component. This method is conservative since it includes heating of the air by the component. Figure C-4 shows one method of mounting the thermocouple. 94 MVME51005E Single Board Computer Installation and Use (6806800A38B) C Thermal Analysis Tape thermocouple wire to top of component Thermocouple junction Air flow PWB Figure C-4.
