Extending the SCSI Bus
The PDX103 extends one or both SCSI buses to include four or eight additional hard
disk drives. The extended bus must be terminated, just as the internal bus is
terminated.
To connect the disk drives in the PDX103, run a SCSI cable from the PDR100
SCSI A (and, where applicable SCSI B) connector to the PDX103 rear panel
connector. Note that there are four connectors on the rear panel, two for each of the
SCSI channels. See Figure 3-18.
Figure 3-18. Rear Panel Drawing of the PDX103 Showing the 4 SCSI Connectors
One connector for each channel serves as the input while the other is then terminated
with the passive termination. See Figure 3-19. The termination is the same one
shipped with the PDR100, which must now be on the PDX103 end of the SCSI bus.
