12 Installing the Tabletop LTO-3 Half-Height Tape Drive
LTO-3 Half-Height Tape Drive Quick Start Guide
2 Depending on the interface configuration of your tabletop drive:
a For 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-3 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.
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.

Examples
3 Verify that the tabletop LTO-3 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.
4 Connect the drive AC power cord to the facility AC power receptacle.
Caution: The LTO-3 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.

both internal and external SCSI devices.
