Description

The CP2000AC54TE Rectifier provides significant efficiency improvements in the Compact Power Line platform of Rectifiers. High-

density front-to-back airflow is designed for minimal space utilization and is highly expandable for future growth. The wide-input

standard product is designed to be deployed internationally. It is configured with both RS485 and dual-redundant I

communications busses that allow it to be used in a broad range of applications. These signals and the 5V auxiliary supply are

isolated from the main output and frame ground. Feature set flexibility makes this rectifier an excellent choice for applications

requiring modular AC to - 48V

intermediate voltages, such as in distributed power.

Control and Status

The Rectifier provides three means for monitor/control: analog,

PMBus™, or the GE Galaxy-based RS485 protocol.

Details of analog control and the PMBus™ based protocol are

provided in this data sheet. GE will provide separate

application notes on the Galaxy RS485 based protocol for

users to interface to the rectifier. Contact your local GE

representative for details.

Signal Reference

Unless otherwise noted, all signals are referenced to

Logic_GRD. See the Signal Definitions Table at the end of this

document for further description of all the signals.

Logic_GRD is isolated from the main output of the power

supply for PMBus communications. Communications and the

5V standby output are not connected to main power return

(Vout(-)) and can be tied to the system digital ground point

selected by the user. (Note that RS485 communications is

referenced to Vout(-), main power return of the power supply).

Logic_GRD is capacitively coupled to Frame_GRD inside the

power supply. The maximum voltage differential between

Logic_GRD and Frame_GRD should be less than 100VDC.

Control Signals

Enable: Controls the main 54VDC output when either analog

control or PMBus protocols are selected, as configured by the

Protocol pin. This pin must be pulled low to turn ON the

rectifier. The rectifier will turn OFF if either the Enable or the

ON/OFF pin is released. This signal is referenced to Logic_GRD.

In RS485 mode this pin is ignored.

ON/OFF: This is a shorter pin utilized for hot-plug applications

to ensure that the rectifier turns OFF before the power pins are

disengaged. It also ensures that the rectifier turns ON only

after the power pins have been engaged. Must be connected

to V_OUT ( - ) for the rectifier to be ON.

Margining: The 54VDC output can be adjusted between 44 –

58VDC by a control voltage on the Margin pin. This control

voltage can be generated either from an external voltage

source, or by forming a voltage divider between 3.3V and

Logic_GRD, as shown in Fig. 13. The power supply includes the

high side pull-up 10k resistor to 3.3VDC. Connecting a resistor

between the margin pin and Logic_GRD will complete the

divider.

An open circuit, or a voltage level > 3.0VDC, on this pin sets the

main output to the factory default setting of 54VDC.

Hardware margining is only effective until software

commanded output voltage changes are not executed.

Software commanded output voltage settings permanently

override the hardware margin setting until power to the

internal controller is interrupted, for example if input power or

bias power is recycled.

The controller always restarts into its default configuration,

programmed to set the output as instructed by the margin pin.

Subsequent software commanded settings permanently

override the margin pin. Adding a resistor between margin and

Vout(-) is an ideal way of changing the factory set point of the

rectifier to whatever voltage level is desired by the user.

Figure 13. Diagram showing how output can be margined

using Vcontrol adjustment.

Module Present Signal: This signal has dual functionality. It

can be used to alert the system when a rectifier is inserted. A

500 resistor is present in series between this signal and

Logic_GRD. An external pull-up should not raise the voltage on

the pin above 0.25VDC. When the voltage on this pin exceeds

1VDC, the write_protect feature of the EEPROM is enabled.

8V_INT: Single wire connection between modules, Provides

bias to the DSP of an unpowered module.

Reset: This is a PCA9541 multiplexer function utilized during

PMBus communications. If momentarily grounded (Logic_GRD),

the multiplexer would reset itself.

Protocol: Establishes the communications mode of the

rectifier, between analog/PMBus and RS485 modes. For RS485,

connect a 10k pull-down resistor from this pin to V_OUT( - ).

For analog/PMBus leave the pin open. Do not tie this signal pin

to V_OUT( - ) because that connection configures the internal

DSP into a reprogrammed state.

Unit Address: Each module has an internal 10k resistor

pulled up between unit_address and 3.3VDC. A resistor

between unit_address and Vout(-) sets the appropriate unit

address.

Shelf Address: By applying the required voltage between the

shelf address pin and Vout(-), up to 8 different shelves and so

up to 32 different modules can be addressed using either the

PMBus or GE Galaxy based RS485 protocol.

PMBus addressing is limited to a maximum of 8 modules and

so the software decodes the shelf address setting into either

shelf 0 or shelf 1 in PMBus applications. If more than two

shelves are paralleled, the user must separate the I2C lines so

that address conflicts do not occur.

Status Signals

Power Capacity: A HI on this pin indicates that the rectifier

delivers high line rated output power; a LO indicates that the

rectifier is connected to low line configured for 1200W

operation.

Power Fail Warning: This signal is HI when the main output is

being delivered and goes LO for the duration listed in this data

sheet prior to the output decaying below the listed voltage

level.

Fault: This signal goes LO for any failure that requires rectifier

replacement. These faults may be due to:

 Fan failure

 Over-temperature warning

 Over-temperature shutdown

 Over-voltage shutdown

 Internal Rectifier Fault

Digital Feature Descriptions

PMBus™ compliance: The power supply is fully compliant to

the Power Management Bus (PMBus™) rev1.2 requirements

with the following exceptions:

The power supply continuously updates its STATUS and ALARM

registers to the latest state in order to capture the ‘present’

state of the power supply. There are a number of indicators,

such as those indicating a communications fault (PEC error,

data error) that do not get cleared until specifically instructed

by the host controller sending a clear_faults command. A ‘bit’

indicator notifies the user if the STATUS and ALARM registers

changed since the last ‘read’ by the host controller.

For example, if a voltage surge causes a momentary shutdown

for over voltage the power supply will automatically restart if

the ‘auto_restart’ feature is invoked. During the momentary

shutdown the power supply issues an Alert# indicating to the

system controller that a status change has occurred. If the

system controller reads back the STATUS and ALARM registers

while the power supply is shut down it will get the correct fault

condition. However, inquiry of the state of the power supply

after the restart event would indicate that the power supply is

functioning correctly. The STATUS and ALARM indicators did

not freeze at the original shutdown state and so the reason for

the original Alert# is erased. The restart ‘bit’ would be set to

indicate that an event has occurred.

The power supply also clears the STATUS and ALARM registers

after a successful read back of the information in these

registers, with the exception of communications error alarms.

This automated process improves communications efficiency

since the host controller does not have to issue another

clear_faults command to clear these registers.

Dual, redundant buses: Two independent I2C lines provide

true communications bus redundancy and allow two

independent controllers to sequentially control the power

supply. For example, a short or an open connection in one of

the I2C lines does not affect communications capability on the

other I2C line. Failure of a ‘master’ controller does not affect the

power supplies and the second ‘master’ can take over control

at any time.

Using the PCA9541 multiplexer: Transition between the two

I2C lines is provided by the industry standard PCA9541 I2C

master selector multiplexer. Option 01 of the device code is

supplied which, upon start-up, connects channel 0 to the

power supply. In this fashion applications using only a single

I2C line can immediately start talking across the bus without

first requiring to reconfigure the multiplexer.

Figure 14. Diagram showing conceptual representation

of the dual I2C bus system.

Control can be taken over at any time by a specific ‘master’

even during data transmission to the other ‘master’. The

‘master’ needs to be able to handle incomplete transmissions

in the multi-master environment in case switching should

commence in the middle of data transmission.

Master/Slave: The ‘host controller’ is always the MASTER.

Power supplies are always SLAVES. SLAVES cannot initiate

communications or toggle the Clock. SLAVES also must

respond expeditiously at the command of the MASTER as

required by the clock pulses generated by the MASTER.

Clock stretching: The ‘slave’ µController inside the power

supply may initiate clock stretching if it is busy and it desires to

delay the initiation of any further communications. During the

clock stretch the ‘slave’ may keep the clock LO until it is ready

to receive further instructions from the host controller. The

maximum clock stretch interval is 25ms.

The host controller needs to recognize this clock stretching,

and refrain from issuing the next clock signal, until the clock

line is released, or it needs to delay the next clock pulse

beyond the clock stretch interval of the power supply.

Note that clock stretching can only be performed after

completion of transmission of the 9th ACK bit, the exception

being the START command.

Figure 14. Example waveforms showing clock stretching.

Communications speed: Both 100kHz and 400kHz clock rates

are supported. The power supplies default to the 100kHz clock

rate.

Packet Error Checking: The power supply will not respond to

commands without the trailing PEC. The integrity of

communications is compromised if packet error correction is

not employed. There are many functional features, including

turning OFF the main output, that require validation to ensure

that the correct command is executed.

PEC is a CRC-8 error-checking byte, based on the polynomial

C(x) = x8 + x2 + x + 1, in compliance with PMBus™

requirements. The calculation is based in all message bytes,

including the originating write address and command bytes

preceding read instructions. The PEC is appended to the

message by the device that supplied the last byte.

SMBusAlert#: The power supply can issue SMBAlert# driven

from either its internal micro controller (µC) or from the

PCA9541 I2C bus master selector. That is, the SMBAlert# signal

of the internal µC funnels through the PCA9541 master

selector that buffers the SMBAlert# signal and splits the signal

to the two SMBAlert# signal pins exiting the power supply. In

addition, the PCA9541 signals its own SMBAlert# request to

either of the two SMBAlert# signals when required.

Non-supported commands: Non supported commands are

flagged by setting the appropriate STATUS bit and issuing an

SMBAlert# to the ‘host’ controller.

Data out-of-range: The power supply validates data settings

and sets the data out-of-range bit and SMBAlert# if the data is

not within acceptable range.

SMBAlert# triggered by the µC: The µC driven SMBAlert#

signal informs the ‘master/host’ controller that either a STATE

or ALARM change has occurred. Normally this signal is HI. The

signal will change to its LO level if the power supply has

changed states and the signal will be latched LO until the

power supply receives a ‘clear’ instruction as outlined below. If

the alarm state is still present after the ‘clear_faults’ command

has been received, then the signal will revert back into its LO

level again and will latch until a subsequent ‘clear’ signal is

received from the host controller.

The signal will be triggered for any state change, including the

following conditions;

 VIN under or over voltage

 Vout under or over voltage

 IOUT over current

 Over Temperature warning or fault

 Fan Failure

 Communication error

 PEC error

 Invalid command

 Internal faults

The power supply will clear the SMBusAlert# signal (release the

signal to its HI state) upon the following events:

 Completion of a ‘read_status’ instruction

 Receiving a CLEAR_FAULTS command

 The main output recycled (turned OFF and then ON) via

the ENABLE signal pin

 The main output recycled (turned OFF and then ON) by the

OPERATION command

SMBAlert# triggered by the PCA9541: If clearing the Alert#

signal via the clear_faults or read back fails, then reading back

the Alert# status of the PCA9541 will be necessary followed by

clearing of the PCA9541 Alert#.

The PCA9541 can issue an Alert# even when single bus

operation is selected where the bus master selector has not

been used or addressed. This may occur because the default

state of the PCA9541/01 integrated circuit issues Alert# to both

i2C lines for all possible transitioning states of the device. For

example, a RESET caused by a glitch would cause the Alert# to

be active.

If the PCA9541 is not going to be used in a specific application

(such as when only a single I2C line is utilized), it is imperative

that interrupts from the PCA9541 are de-activated by the host

controller. To de-activate the interrupt registers the PCA9541

the ‘master’ needs to address the PCA9541 in the ‘write’ mode,

the interrupt enable (IE) register needs to be accessed and the

interrupt masks have to be set to HI ‘1’. (Note: do not mask bit

0 which transmits Alert# from the power supply). This

command setting the interrupt enable register of the PCA9541

is shown below;

There are two independent interrupt enable (IE) registers, one

for each controller channel (I2C-0 and I2C-1). The interrupt

independently. That is, channel I2C-0 cannot configure the IE

This command has to be initiated to the PC9541 only once

after application of power to the device. However, every time a

restart occurs the PCA9541 has to be reconfigured since its

default state is to issue Alert# for changes to its internal status.

If the application did not configure the interrupt enable register

the Alert# line can be cleared (de-activated), if it has been

activated by the PCA9541, by reading back the data from the

interrupt status registers (Istat).

Refer to the PCA9541 data sheet for further information on

how to communicate to the PCA9541 multiplexer.

Please note that the PCA9541 does not support Packet Error

Checking (PEC).

Re-initialization: The I2C code is programmed to re-initialize if

no activity is detected on the bus for 5 seconds. Re-

initialization is designed to guarantee that the I2C µController

does not hang up the bus. Although this rate is longer than the

timing requirements specified in the SMBus specification, it

had to be extended in order to ensure that a re-initialization

would not occur under normal transmission rates. During the

few µseconds required to accomplish re-initialization the I2C

µController may not recognize a command sent to it. (i.e. a

start condition).

Global broadcast: This is a powerful command because it can

instruct all power supplies to respond simultaneously in one

command. But it does have a serious disadvantage. Only a

single power supply needs to pull down the ninth acknowledge

bit. To be certain that each power supply responded to the

global instruction, a READ instruction should be executed to

each power supply to verify that the command properly

executed. The GLOBAL BROADCAST command should only be

executed for write instructions to slave devices.

Note: The PCA9541 i2c master selector does not respond to the

GLOBAL BROADCAST command.

Read back delay: The power supply issues the SMBAlert #

notification as soon as the first state change occurred. During

an event a number of different states can be transitioned to

before the final event occurs. If a read back is implemented

rapidly by the host a successive SMBAlert# could be triggered

by the transitioning state of the power supply. In order to avoid

successive SMBAlert# s and read back and also to avoid

reading a transitioning state, it is prudent to wait more than 2

seconds after the receipt of an SMBAlert# before executing a

read back. This delay will ensure that only the final state of the

power supply is captured.

Successive read backs: Successive read backs to the power

supply should not be attempted at intervals faster than every

one second. This time interval is sufficient for the internal

processors to update their data base so that successive reads

provide fresh data.

Device ID: Address bits A2, A1, A0 set the specific address of

the power supply. The least significant bit x (LSB) of the address

byte configures write [0] or read [1] events. In a write

command the system instructs the power supply. In a read

command information is being accessed from the power

supply.

data value from the controller and x is the ‘real’ value either

being set or returned.

For example, to set the output voltage to 50.45VDC, Multiply the

least 2 seconds, and then turn back ON. All alarms and

shutdowns are cleared during a restart.

Clear_faults (03h): This command clears information bits in

the STATUS registers, these include:

 Isolation OK

 Isolation test failed

 Restarted OK

 Invalid command

 Invalid data

 PEC error

Vout_Command (21h) : This command is used to change the

output voltage of the power supply. Changing the output

voltage should be performed simultaneously to all power

supplies operating in parallel using the Global Address

(Broadcast) feature. If only a single power supply is instructed

to change its output, it may attempt to source all the required

power which can cause either a power limit or shutdown

condition.

Software programming of output voltage overrides the set

point voltage configured during power_up. The program no

longer looks at the ‘margin pin’ and will not respond to any

hardware voltage setting. The default state cannot be

accessed any longer unless power is removed from the DSP.

To properly hot-plug a power supply into a live backplane, the

system generated voltage should get re-configured into either

the factory adjusted firmware level or the voltage level

reconfigured by the margin pin. Otherwise, the voltage state

of the plugged in power supply could be significantly different

than the powered system.

Voltage margin range: 42VDC – 58 VDC.

A voltage programming example: The task: set the output

voltage to 50.45VDC

The constants for voltage programming are: m = 400, b and R

= 0. Multiply the desired set point by the m constant, 50.45 x

400 = 20,180. Convert this binary number to its hex equivalent:

20,180b = 4ED4h. Transmit the data LSB first, followed by MSB,

0 x D44Eh.

Vout_OV_fault_limit (40h) : This command sets the Output

Overvoltage Shutdown level.

Manufacturer-Specific PMBusTM Commands

Many of the manufacturer-specific commands read back more

than two bytes. If more than two bytes of data are returned,

the standard SMBusTM Block read is utilized. In this process, the

Master issues a Write command followed by the data transfer

from the power supply. The first byte of the Block Read data

field sends back in hex format the number of data bytes,

exclusive of the PEC number, that follows. Analog data is

always transmitted LSB followed by MSB. A No-ack following

the PEC byte signifies that the transmission is complete and is

being terminated by the ‘host’.

Read_status (D0h) : This ‘manufacturer specific’ command is

the basic read back returning STATUS and ALARM register

data, output voltage, output current, and internal temperature

data in a single read.

LEDS test ON (D2h) : Will turn-ON simultaneously the four

front panel LEDs of the Power supply sequentially 7 seconds

ON and 2 seconds OFF until instructed to turn OFF. The intent

of this function is to provide visual identification of the power

supply being talked to and also to visually verify that the LEDs

operate and driven properly by the micro controller.

LEDS test OFF (D3h) : Will turn-OFF simultaneously the four

front panel LEDs of the Power supply.

Service LED ON (D4h) : Requests the power supply to flash-ON

the Service (ok-to-remove) LED. The flash sequence is

approximately 0.5 seconds ON and 0.5 seconds OFF.

Service LED OFF (D5h) : Requests the power supply to turn OFF

the Service (ok-to-remove) LED.

Enable write (D6h) : This command enables write permissions

into the upper ¼ of memory locations for the external

EEPROM. A write into these locations is normally disabled until

commanded through I2C to permit writing into the protected

area. A delay of about 10ms is required from the time the

instruction is requested to the time that the power supply

actually completes the instruction.

See the FRU-ID section for further information of content

written into the EEPROM at the factory.

Disable write (D7h) : This command disables write permissions

into the upper ¼ of memory locations for the external

EEPROM.

Unit in Power Limit or in Current Limit: When output voltage

is > 36VDC the Output LED will continue blinking.

When output voltage is < 36VDC, if the unit is in the RESTART

mode, it goes into a hiccup. When the unit is ON the output

LED is ON, when the unit is OFF the output LED is OFF.

When the unit is in latched shutdown the output LED is OFF.

Inhibit_restart (D8h) : The Inhibit-restart command directs

the power supply to remain latched off for over_voltage,

over_temperature and over_current. The command needs to

be sent to the power supply only once. The power supply will

remember the INHIBIT instruction as long as internal bias is

active.

Restart after a lachoff: To restart after a latch_off either of

four restart mechanisms are available. The hardware pin

Enable may be turned OFF and then ON. The unit may be

commanded to restart via i2c through the Operation

command by first turning OFF then turning ON . The third way

to restart is to remove and reinsert the unit. The fourth way is

to turn OFF and then turn ON ac power to the unit. The fifth

way is by changing firmware from latch off to restart. Each of

these commands must keep the power supply in the OFF state

for at least 2 seconds, with the exception of changing to

restart.

A successful restart shall clear all alarm registers, set the

restarted successful bit of the Status_2 register.

A power system that is comprised of a number of power

supplies could have difficulty restarting after a shutdown event

because of the non-synchronized behavior of the individual

power supplies. Implementing the latch-off mechanism

permits a synchronized restart that guarantees the

simultaneous restart of the entire system.

A synchronous restart can be implemented by;

1. Issuing a GLOBAL OFF and then ON command to all power

supplies,

2. Toggling Off and then ON the ENABLE signal

3. Removing and reapplying input commercial power to the

entire system.

The power supplies should be turned OFF for at least 20 – 30

seconds in order to discharge all internal bias supplies and

reset the soft start circuitry of the individual power supplies.

Auto_restart (D9h) : Auto-restart is the default configuration

for overvoltage, overcurrent and overtemperature shutdowns.

However, overvoltage has a unique limitation. An overvoltage

shutdown is followed by three attempted restarts, each restart

delayed 1 second, within a 1 minute window. If within the 1

minute window three attempted restarts failed, the unit will

latch OFF. If within the 1 minute less than 3 shutdowns

occurred then the count for latch OFF resets and the 1 minute

window starts all over again.

This command resets the power supply into the default auto-

restart configuration.

Isolation test (DAh): This command verifies functioning of

output OR’ing. At least two paralleled power supplies are

required. The host should verify that N+1 redundancy is

established. If N+1 redundancy is not established the test can

fail. Only one power supply should be tested at a time.

Verifying test completion should be delayed for approximately

30 seconds to allow the power supply sufficient time to

properly execute the test.

Failure of the isolation test is not considered a power supply

FAULT because the N+1 redundancy requirement cannot be

verified. The user must determine whether a true isolation fault

indeed exists.

of the clock stretch feature.

None supported commands or invalid data: The power

supply notifies the MASTER if a non-supported command has

been sent or invalid data has been received. Notification is

implemented by setting the appropriate STATUS and ALARM

registers and setting the SMBAlert# flag.

Fault Management

The power supply records faults in the STATUS and ALARM

registers above and notifies the MASTER controller as

described in the Alarm Notification section of the non-

conforming event.

The STATUS and ALARM registers are continuously updated

with the latest event registered by the rectifier monitoring

circuits. A host responding to an SMBusALERT# signal may

receive a different state of the rectifier if the state has changed

from the time the SMBusALERT# has been triggered by the

rectifier.

The power supply differentiates between internal faults that

are within the power supply and external faults that the

power supply protects itself from, such as overload or input

voltage out of limits. The FAULT LED, FAULT PIN or i2c alarm is

not asserted for EXTERNAL FAULTS. Every attempt is made to

annunciate External Faults. Some of these annunciations can

be observed by looking at the input LEDs. These fault

categorizations are predictive in nature and therefore there is

a likelihood that a categorization may not have been made

correctly.

Input voltage out of range: The Input LED will continue

blinking as long as sufficient power is available to power the

LED. If the input voltage is completely gone the Input LED is

OFF.

State Change Definition

A state_change is an indication that an event has occurred

that the MASTER should be aware of. The following events

shall trigger a state_change;

 Initial power-up of the system when AC gets turned ON .

This is the indication from the rectifier that it has been

turned ON. Note that the master needs to read the status

of each power supply to reset the system_interrupt. If the

power supply is back-biased through the 8V_INT or the

5VSTB it will not issue an SMBALERT# when AC power is

turned back ON.

 Whenever the power supply gets hot-plugged into a

working system. This is the indicator to the system

(MASTER) that a new power supply is on line.

 Any changes in the bit patterns of the STATUS and ALARM

registers are a STATUS change which triggers the

SMBALERT# flag. Note that a host-issued command such

as CLEAR_FAULTS will not trigger an SMB

Hot plug procedures

Careful system control is recommended when hot plugging a

power supply into a live system. It takes about 15 seconds for

a power supply to configure its address on the bus based on

the analog voltage levels present on the backplane. If

communications are not stopped during this interval, multiple

power supplies may respond to specific instructions because

the address of the hot plugged power supply always defaults

to xxxx000 (depending on which device is being addressed

within the power supply) until the power supply configures its

address.

The recommended procedure for hot plug is the following: The

system controller should be told which power supply is to be

removed. The controller turns the service LED ON, thus

informing the installer that the identified power supply can be

removed from the system. The system controller should then

poll the module_present signal to verify when the power

supply is re-inserted. It should time out for 15 seconds after

this signal is verified. At the end of the time out all

communications can resume.

Predictive Failures

Alarm warnings that do not cause a shutdown are indicators

of potential future failures of the power supply. For example, if

a thermal sensor failed, a warning is issued but an immediate

shutdown of the power supply is not warranted.

Another example of potential predictive failure mechanisms

can be derived from information such as fan speed when

multiple fans are used in the same power supply. If the speed

of the fans varies by more than 20% from each other, this is an

indication of an impending fan wear out.

The goal is to identify problems early before a protective

shutdown would occur that would take the power supply out

of service.

External EEPROM

A 64k-bit EEPROM is provided across the I2C bus. This EEPROM

is used for both storing FRU_ID information and for providing a

scratchpad memory function for customer use.

Functionally the EEPROM is equivalent to the ST M34D64 part

that has its memory partitioned into a write protected upper ¼

of memory space and the lower ¾ section that cannot be

protected. FRU_ID is written into the write protected portion of

memory.

Write protect feature: Writing into the upper 1/4 of memory

can be accomplished either by hardware or software.

The power supply pulls down the write_protect (Wp) pin to

ground via a 500 resistor between the ‘module_present’

signal pin and Logic_GRD (see the Module Present Signal

section of Input Signals). Writing into the upper ¼ of memory

can be accomplished by pulling HI the module_present pin.

An alternative, and the recommended approach, is to issue the

Enable_write command via software.

Page implementation: The external EEPROM is partitioned into

32 byte pages. For a write operation only the starting address

is required. The device automatically increments the memory

address for each byte of additional data it receives. However,

if the 32 byte limit is exceeded the device executes a wrap-

around that will start rewriting from the first address specified.

Thus byte 33 will replace the first byte written, byte 34 the

second byte and so on. One needs to be careful therefore not

to exceed the 32 byte page limitation of the device.
