3.2 Unit Computer and Memory

The Unit Computer controls the Ethernet infrastructure and hosts the management application. It is a Pow-
erPC 405EX with following features:
• 600MHz core frequency
• PCIe management connection to Ethernet Switch
• GbE connections to front management port and Ethernet Switch
The Unit Computer is equipped with following peripherals:
• 512MB DDR2 Memory with 400MHz data rate and ECC
• 64MB NOR Flash Memory for two Firmware images
• 1024MB NAND Flash for high volume storage (TFTP Server applications) with high frequency read
• Real Time Clock with integrated oscillator, powered by a capacitor with up to 1 week of back up power

3.3 IPMI

The CP6930 board supports an intelligent hardware management system, based on the Intelligent Platform
Management Interface Specification 1.5. The hardware management system provides the ability to manage
the power, cooling and interconnect needs of intelligent devices, to monitor events and to log events to a
central repository intelligent FRU (Field Replaceable Unit).
The Peripheral Manager is a 16-bit microcontroller with on chip memory of 512 Kbyte Flash and 40Kbyte
SRAM. It provides several I²C interfaces for access to sensors and IPMBL busses. Board voltage, current and
temperature monitoring are accomplished through internal and external sensors. An LPC bus connects the
PM to the Unit Computer.
The following section provides a listing of all inputs to the IPMI subsystem for H/W supervision.
• Thermal Sensors
• Reset status of the Unit Computer
• Power Status, the PM reads all supply voltages and status signals for possible failure and value report-
ing
• Ethernet Link status
• SFP status and control signals
• CompactPCI Handle switch (Hot Swap)
The PM uses the following outputs to control the CP6930:
• Power enable for the payload power
• Hot swap LED
• LED ACTIVITY and LED HEALTHY
• Unit Computer reset
