SCSI Backplane
The 1-inch high SCSI backplane included in the system supports
three Ultra160 SCSI devices. The backplane design incorporates a
hot-swap feature to allow easy installation of external 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
Out connectors available for the SCA SCSI hard disks. The
hard disks are extenally accessible from the front panel.
