ding on the interface configuration of your tabletop drive:
a F
or the parallel SCSI tabletop drive:
• Attach the SCSI IN interface cable to one of the 68-pin parallel SCSI interface
connectors on the back of the drive.
• Attach either the SCSI OUT interface cable or a SCSI terminator to the other
parallel SCSI interface connector on the back of the drive.
If the tabletop LTO-4 (Model B) Half-Height Tape Drive is the last or only
device in a SCSI chain, you must install a 68-pin low voltage differential
(LVD) terminating plug on the unused parallel SCSI connector.
See figure 11
for tabletop parallel SCSI bus termination examples.
Caution: The LTO-4 (Model B) Half-Height Tape Drive with the parallel SCSI
interface is a low voltage differential (LVD) SCSI device. Install it
only in LVD environments. Plugging an LVD drive into a high
voltage differential (HVD) bus makes the entire bus nonfunctional
and may permanently damage the drive or other SCSI devices on
the bus.
b For the SAS tabletop drive, attach the external SAS interface cable to the 26-pin
SFF-8088 mini-SAS connector on the back of the drive.

Example 1: SCSI termination in a system
that has only external SCSI devices.
Example 2: SCSI termination in a system that has
both internal and external SCSI devices.
3 Verify that the tabletop LTO-4 (Model B) Half-Height Tape Drive AC power switch is
set to the off position, and connect the AC power cord to the power connector on
the back of the drive.
