5 System Monitoring and Control
The cPB4612 has an IPMI System Monitor that complies with PICMG
®
2.9 specification, and complies
with IPMI Specification 1.5. This allows a PICMG 2.9 compliant chassis that utilizes a chassis manager,
or Baseboard Management Controller (BMC) to detect the presence of the cPB4612 and make Field
Replaceable Unit (FRU) information, and Sensor Device Records (SDR’s) available. Sensors monitor
voltages, CPU and system temperature, and other inputs, including the front latch, which can generate
events that are recorded in the BMC’s System Event Log (SEL). The IPMI System Monitor has both an
IPMB and a dedicated basic serial interface, so that it is possible for the cPB4612 to acquire FRU and
sensor information directly from the IPMI System Monitor. The firmware on the IPMI System Monitor can
be upgraded via the serial interface or over IPMB.
