Intel® Server Platform SR6850HW4 TPS

System Overview

2.7.2Hot Swap Controller

Two hot-swap controllers are on the SCSI Backplane Board. The primary function of each hot-swap controller is as follows:

ƒImplements the SAF-TE command set

ƒControls the SCSI hard disk drive power, activity and fault LEDs

ƒProvides a path for management information via the SCSI bus

ƒRetrieves hard disk drive fault status, SCSI Backplane Board temperature, and fan failure information via IPMB

ƒQueries the status of the Power Distribution Board by retrieving information from the IMM via IPMB

ƒControls hard disk drive power-on and power-down, facilitating hot-swapping
