36000-580-03 B Zircon PM
Product Description
Zircon PM is an intelligent peripheral management
controller for CompactPCI I/O boards and other peripheral
devices such as chassis, front panels, power supplies and
fans. It meets all the requirements defined in the
CompactPCI System Management Specification including
hardware and firmware support for the IPMI specification.
Combining the QLogic Zircon Baseboard Management
Controller (BMC), which resides on CompactPCI system
boards, with Zircon PM forms a complete management
solution for CompactPCI-based systems.
Zircon PM supports the “Standard Node” as defined by
the System Management specification. This includes
compliance with electrical and functional requirements,
which enables Zircon PM to maintain stable system
management operation during board insertion and
extraction. It also provides glitch, or signal transient
rejection; built-in mechanisms to recover from
transmission line violations such as aborted transfers and
stuck signal lines on the IPMB. General purpose
input/output pins may be used for geographical slot
addressing and shelf addressing as defined by the
CompactPCI and Computer Telephony specifications,
respectively.
Zircon PM also features embedded functions that provided
advanced system management capabilities such as fan
speed monitoring and control, voltage monitoring, and
board power control.
Zircon PM’s high integration, extensible design and
software support make it the ideal peripheral management
controller for Embedded Computer applications such as
telecommunications and voice processing equipment.
Other applications include peripheral devices such as
power supplies and front panel displays, which need to
support IPMI.
The Zircon PM block Diagram is illustrated in figure 1.

CompactPCI System Management Architecture
The CompactPCI System Management Specification in conjunction with the IPMI specification defines the
management architecture for CompactPCI systems. These specifications standardize the various interfaces, protocols
and electrical requirements allowing for interoperability between chassis, CPU boards and I/O boards. IPMI-
compatible baseboard management controller (BMC) resides on the CPU (Central Processor Unit) board and a
peripheral management controller (PMC) resides on the I/O boards. A serial interface (I2C) is the physical transport
for board to board communication. The diagram in figure 2 shows this systems management implementation.

Applications
Zircon PM is an IPMI-based peripheral management controller that resides on CompactPCI I/O boards. Other
applications include use as a management controller for front panels, power supplies and fan modules which require
intelligent management capabilities and IPMI support. Figure 3 shows a typical application for Zircon and the
Zircon PM within a CompactPCI environment.
