default for the drive is SCSI ID 6. The SCSI ID is set with Jumpers as shown below.

If the tape drive is going to share the SCSI bus with other devices, check the SCSI ID numbers used by the other devices,

then set the drive’s SCSI ID to a number that is not being used.

Note: Notice that the SCSI host adapter uses ID 7.

For optimal performance Dell recommends that the tape drive be the only device on the SCSI bus.

SCSI Termination

A SCSI bus must be terminated at both ends. The SCSI Host Adaptor provides the termination for one end but the tape

drive does not provide termination for the other. Therefore, if the tape drive is the last device on the bus, a cable with

proper LVD termination is required within 10 cm of the drive as illustrated below.

PowerVault LTO-2-024 has a combined SCSI-LVD/SE interface embedded. The PC-98 Specification specifies that the

termination of the SCSI bus system is a part of the SCSI-cable and not a part of the SCSI-device.
