SC SI Ba ckplane Daughter Card
Downloaded from www.Manualslib.com
Slide the daughter card into the drive bay and lock the card into place by closing the
9
retention lever on the card's front edge (see Figure 1-4).
The four connectors on the SCSI backplane board are designated as SCSI ID 0
through SCSI ID 3 (see Figure 1-1). If a fifth hard-disk drive is installed in the
peripheral bay, it is identified as SCSI ID 4.
To configure the drives in a split 2 x 2 configuration (1 x 2 and 1 x 3 in a five-drive
system), you must connect two SCSI host adapters to the SCSI backplane board. The
host adapter attached to connector SCSIB on the backplane controls slots SCSI ID 0
and SCSI ID 1, while the host adapter connected to connector SCSIA controls slots
SCSI ID 2, SCSI ID 3, and the fifth drive slot, SCSI ID 4 (see Figure 1-5).
If you are connecting the integrated SCSI host adapter to the SCSI backplane,
connect the cable leading from connector SCSIA on the system board to connector
SCSIB on the SCSI backplane. Connect the cable leading from connector SCSIB on
the system board to connector SCSIA on the SCSI backplane.
