SCSI backplane components

The SCSI backplane connects the SCA-2 LVD SCSI drives to the SCSI RAID controller or the SCSI controllers on the system board. The backplane provides automatic SCSI address setting and allows hot-swapping of SCSI drives. Figure 10 shows the back of the backplane where the drives connect.

If the RAID cage is included as part of the server configuration, see the Quick Hot-swap Installation Guide for information on how to configure the quick hot-swap backplane.
