QLogic* GEM359* SCSI Hot-swap Controller
The QLogic GEM359 Hot-swap Controller resides on the SCSI backplane board. The primary
functions of the GEM359 are as follows:
• Implements the SAF-TE command set
• Controls the SCSI hard drive fault LEDs
• Provides a path for management information via the SCSI
• Retrieves hard drive fault status, SCSI backplane temperature, and fan failure information
via the IPMB
• Queries the status of the power distribution board by retrieving information from the BMC
via the IPMB
• Controls hard drive power-on and power-down, facilitating hot-swapping
