Access to the monitored information so system management software can poll
and retrieve the present status of the platform.
Functions for the front-side system controls and indicators. These functions
include control of system power, hard-resets, Power LED displays, cooling fault
detection, general fault detection, and power fault LED displays. The BMC
provides this control both when the system is powered down and is functioning
on standby power only, and when the system is powered up.
Access to the non-volatile Sensor Data Record (SDR) Repository. SDRs provide
information that the system management software uses to automatically
configure itself for the number and type of Intelligent Platform Management
Interface (IPMI) sensors in the system (e.g. temperature and voltage sensors).
