The BMC provides an IPMI 2.0 compatible watchdog timer which can prevent the system from system
hanging.
BMC is in charge of fan speed control. The fan speed can be modified by varying the duty cycle of PWM
signal. The fan speed control algorithm mainly refers to the readings of on-board temperature sensors.
The BMC implements an interface for logical FRU inventory devices as specified in IPMI 2.0 specification.
This functionality provides commands for system administrators to access and management the FRU
inventory information.
