2.7.2 Hot Swap Controller
Two hot-swap controllers are on the SCSI Backplane Board. The primary function of each
hot-swap controller is as follows:
ƒ Implements the SAF-TE command set
ƒ Controls the SCSI hard disk drive power, activity and fault LEDs
ƒ Provides a path for management information via the SCSI bus
ƒ Retrieves hard disk drive fault status, SCSI Backplane Board temperature, and fan
failure information via IPMB
ƒ Queries the status of the Power Distribution Board by retrieving information from the
IMM via IPMB
ƒ Controls hard disk drive power-on and power-down, facilitating hot-swapping
