SCSI Backplane

The two SCSI backplane supports three Ultra160 SCA SCSI hard

disks each for a total of six. The backplane design incorporates a

hot-swap feature to allow easy connection or removal of SCA SCSI

hard disks. The LED connector on the backplane connects to the

front panel LEDs to indicate HDD access, HDD failure, thermal failure,

and fan failure.

80-pin SCA SCSI connectors available for

SCA SCSI hard disks. The hard disks are

externally accessible from the front of the

server.
