The board also contains EEPROM FRU information storage. Server Management The Baseboard Management Controller (BMC) monitors system platform management events and logs their occurrences in the non-volatile System Event Log (SEL). This includes events such as over-temperature and over-voltage conditions, and fan failures. The BMC can also provide the interface to the monitored information so system management software can poll and retrieve the present status of the platform. The BMC also provides the interface to the non-volatile Sensor Data Record (SDR) Repository. Sensor Data Records provide a set of information that system management software can use to automatically configure itself for the number and type of IPMI sensors (such as temperature and voltage sensors) in the system. 57

Power Distribution Board
The power distribution board provides docking connectors for the hot-swappable power supply
modules and distributes power to the main board and SCSI backplane. The board also contains
EEPROM FRU information storage.
Server Management
The Baseboard Management Controller (BMC) monitors system platform management events and
logs their occurrences in the non-volatile System Event Log (SEL). This includes events such as
over-temperature and over-voltage conditions, and fan failures. The BMC can also provide the
interface to the monitored information so system management software can poll and retrieve the
present status of the platform.
The BMC also provides the interface to the non-volatile Sensor Data Record (SDR) Repository.
Sensor Data Records provide a set of information that system management software can use to
automatically configure itself for the number and type of IPMI sensors (such as temperature and
voltage sensors) in the system.
