Installing a SCSI Bus and SCSI Devices
This section outlines the followingsteps to physically install a SCSI bus on your
system:
•
Installingconfiguration jumpers on each external SCSI tape and/or disk drive
•
Connectingthe SCSI bus cable in a daisy-chain to the subsystems and
stand-alone devices
•
Terminatinga SCSI bus
To perform each step, you will need the device- and subsystem-specific
documentation listed in
Guide to AViiON
and DG/UX
System Documentation
for
each bus component.
The next section in this chapter describes how to connect an external SCSI bus to your
computer unit.
Before you begin physically installing your SCSI bus and SCSI devices, plan your
cablingscheme(s) and assign SCSI ID numbers to each device accordingto the rules
described in the precedingsections of this chapter. Make certain to assign ID numbers
compatible with any application software requirements planned for your system.
Figure 4Ć6 shows a sample AViiON 530 and 4600 series SCSI layout that adheres to
SCSI bus cable and device identification rules.
