interface.
This guide references the instructions for installing the 1U Rackmount
enclosure in an equipment rack, and provides the procedures for:
• Connecting the drive interface and power cables
• Installing a second tape drive into the 1U Rackmount enclosure

SCSI Cable Configurations
The 1U rackmount enclosure supports the operation of two tape drives on either one or
two SCSI buses. Two internal 2-port SCSI cables are installed in the enclosure and ready
for tape drive connections depending on your configuration.

• Connecting One Drive per SCSI Bus
Connecting Two Drives per SCSI Bus
Use the configuration shown in Figure 18 when connecting both tape drives to the same
SCSI bus.

Note: When adding a second tape drive for configurations using a single SCSI bus,
unplug the SCSI cable from tape drive 1, pass the end of the cable through the
internal rackmount enclosure openings, and connect the end port to tape drive
2. Then plug the middle port into tape drive 1. The SCSI terminator is at the end
of the cable and should be behind tape drive 2.
Note: Each SCSI device on the same SCSI bus must have a unique SCSI ID. Be sure that
the SCSI ID is different for each tape drive and that neither is set to SCSI ID 7.
Connecting One Drive per SCSI Bus
Use the configuration shown in Figure 19 when connecting each tape drive to a
separate SCSI bus.

Note: To prevent possible data errors, when there is only one drive on a SCSI bus, the

Caution: To avoid damaging the equipment due to electrostatic discharge, be sure to
practice ESD procedures when handling the tape drive.

Installing the 1U Rackmount Enclosure in a Rack
The rack rails supplied with the 1U rackmount enclosure can be used to install the unit in
racks that have round, square, or threaded holes in the vertical mounting bars. The rails
are identical and may be mounted on either the left or the right side.
Figure 20 Rail Mounting Kit
Components
Tools Required If you are installing the tape enclosure in a rack with unmarked holes in the vertical
mounting bars the following items will make the rack installation easier:
•Pencil
• Tape measure
If you are installing the tape enclosure in a r
mounting bars you will need the following tool:
• 3/16 in. (5mm) flat-blade screwdriver
ack with threaded holes in the vertical
Installation Procedure When installing the enclosure in a rack:
• Start at the bottom of the rack, or at the top of a previously mounted component,
and work upward.
Installing the 1U Rackmount Enclosure in a Rack 15
LTO-3 (Model B), LTO-4 (Model B), and LTO-5
• If possible, install the heaviest components at the bottom and lighter ones toward
the top of the rack.
• Make sure that the rack-mounting rails are level from front to back.
WARNING: To reduce the risk of personal injury or equipment damage, be sure that:
1. The rack leveling jacks are extended to the floor. 2. The full weight of
the rack rests on the leveling jacks. 3. The stabilizing feet are attached to
the rack if it is a single rack installation. 4. The racks are coupled in
multiple rack installations. 5. Only one component is extended at a time.
6. A rack may become unstable if more than one component is extended
for any reason.
Before you begin
If you are installing the 1U rackmount enclosure in a rack with unmarked holes in the
vertical mounting bars, identify and mark the correct mounting holes in the rack before
you begin rail installation.
Caution: It is important to install rack components level. To ensure that the 1U
rackmount enclosure is installed correctly it may be necessary to measure
the height of the correct mounting holes in the front and rear vertical
mounting bars.
Installing the Rackmount Enclosure Mounting Rails
Inner rack rails are the inner portion of the rack rail system that attached to the tape
enclosure.
1 Align the slotted holes on the left and right component rails with the three pins on
the sides of the rack mount enclosure.
2 Slide the component rails toward the rear of the enclosure until they lock into place.

Installing the Rack Rails Installation procedures differ depending on the rack type. The rails are shipped ready for
installation in racks with round or square holes. If the rails are to be installed in racks
with 10-32 threaded holes, the mounting pins must first be removed. Refer to the
following sections for installation instructions for your rack type:
