Baseboard Management Controller (BMC)

Baseboard Management Controller (BMC)

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.

The following is a list of the major functions of the BMC:

System power control (including providing Sleep/Wake push-button interfaces for
ACPI

Platform Event Paging (PEP) / Platform Event Filtering (PEF)

Monitoring:

Power Distribution Board monitoring

Temperature and voltage monitoring

Fan failure monitoring

Processor presence monitoring (no processors installed) and processor temperature
monitoring

Interlock monitoring

Processor core ratio speed setting

Speaker beep capability on standby and when system is powered up

Hot-plug PCI slot status reporting

Chassis control:

General fault light control

Chassis cooling failure light control

Chassis power fault light control

Chassis power light control

Chassis ID LEDs control

System Event Log (SEL) interface

Sensor Data Record (SDR) repository interface
