5.3 Field Replaceable Unit (FRU) Information
Board information, such as serial number, date of manufacture, OEM name, part number, etc., are
retrievable from the FRU. It complies with the IPMI FRU 1.0 Specification. The information in the FRU
can be customized to add other product information, such as asset tag, other part numbers, etc.
5.4 Sensors
The sensors that the cPB4612 supports with the IPMI System Monitor can be retrieved in the Sensor
Data Records (SDR’s) via normal IPMI commands. They include:
System Ambient Temperature
+12V
CPU
Temperature
+1.5V
VTT DDR
+1.8V
CPU
Core
Voltage
ONCTL#
+3.3V
SLOT
+5V
Front
Latch
These sensors (with the exception of ONCTL and SLOT), when enabled by the BMC, will generate
sensor events on the IPMB. These events will normally be logged by the BMC and time-date stamped.
On temperature and voltage sensors, if sensor readings cross any of the non-critical, critical, or non-
recoverable thresholds, the IPMI System Monitor will generate IPMB event data to inform the BMC. The
IPMI System Monitor allows the BMC, via IPMI commands, to override its sensor thresholds
5.5 Firmware
Updates
Firmware updates are possible through either the serial or IPMB interface. A special utility will be
provided should a firmware update be necessary.
