Chapter 2 Installing Internal Tape Drives
Connecting a SCSI Cable

Connecting a SCSI Cable 2
The internal SCSI tape drives can be used with a Wide SCSI interface,
either Low Voltage Differential (LVD) or Single-ended (16-bit Wide
mode).
The tape drive automatically detects whether the SCSI bus is LVD or
single ended. Be sure the SCSI bus is terminated properly.
Connecting to a Wide
SCSI Connector
2
If your computer has a 68-pin wide SCSI connector, attach the interface
cable from the SCSI host controller to the 68-pin SCSI interface connector
on the back of the internal tape drive.

Tape Drive
Note: We strongly recommend that you attach the tape drive to SCSI
controllers that support the SCSI Ultra2 LVD interface only.
Attaching the tape drive to a non-LVD SCSI controller or an 8-
bit Narrow SCSI controller will degrade the performance of
your tape drive and backup operations. Performance will also
be degraded if you attach non-LVD SCSI devices on the same
bus cable as your LVD connection. Do not connect the tape
drive to a disk RAID controller (disk RAID controllers are not
supported). If you install an adapter, we recommend you
purchase a SCSI LVD controller kit that includes the SCSI
cable and terminator.
