Storage Backplane
The storage backplane supports seven hot-swap devices split between two SCSI bus sections
(see Figure 3 - 21). SCSI bus A and SCSI bus B. SCSI bus A is the upper section and consists of four
SCSI device connections. SCSI bus B is the lower bus section and consists of three SCSI device
connections. These buses can be configured as two independent SCSI buses or as one SCSI bus by
installing a wide SCSI jumper cable. (Figures 3 - 22 through 3 - 25 show the available cable
configurations.
Contact the Digital sales representative for ordering information about SCSI cables and devices.
