SCSI Backplane Board
The SCSI backplane board provides a convenient interface between the SCSI
drives and the system board. It includes eight SCSI drive slots to accommodate
the drive trays and two SCSI channels to connect to the system board or SCSI
controller board.
See Sections 2.9.1 and 2.9.2 for more information about the SCSI backplane board.
3.3.1
Features
The backplane board has the following major features:
•
“Hot-swap” feature that allows replacement of a defective hard drive even
while the system is in full operation. This feature requires a RAID controller
board and RAID drivers installed.
•
2 channel configurations that support 4 SCSI hard drives per channel
•
Indicates hard disk drive failure through an LED on the drive tray
•
Supports Ultra2 SCSI SCA (Single Connector Adapter) disk drives
•
SCSI ID strapping that allows wide SCSI HDD ID configuration through the
backplane switches, instead of configuring the individual drive IDs
We recommend setting the IDs on the
backplane board instead of on the individual
drives. See section 3.3.2 for the location of
the SCSI connector ID switches.
If you set the IDs on the backplane board, be
sure to remove all jumper connectors on the
SCSI drive before installing it into the
system.
