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.
Front Side
The front side of the backplane has three
80-pin SCA SCSI connectors available for
SCA SCSI hard disks. The hard disks are
externally accessible from the front of the
server.
