2-4 Quantum DLT 4000 Tape Drive

2.2.1 Set the Rackmount Drive SCSI ID

Each device on the SCSI bus must have a unique SCSI ID address assigned to it.

For specific recommendations for assigning SCSI IDs, refer to the system or SCSI

controller documentation.

Rackmount drives can be configured for SCSI ID addresses that range from 0 to 7

(default=5) in one of two ways:

a) jumper the 10-pin SCSI ID jumper block shown in Figure 2-1, or

b) set the IDs through firmware. If the firmware is set to SCSI ID = 5, then no

jumpers are installed on the SCSI ID jumper block.

This subsection discusses setting the SCSI ID on the rackmount drive via the

jumper block. Table 2-1 lists the SCSI ID address and jumper settings.

NOTES

The default setting for the tape drive is SCSI ID 5; the host adapter is

typically SCSI ID 7.

A jumper must be installed across Pins 9-10 (Remote ID Present pins)

for the host to recognize any SCSI ID selections from this jumper

block.
