1U Rackmount Enclosure
Installation Guide
The 1U Rackmount enclosure is provided with either one or two of the
following supported tape drives already installed:
• LTO-3 (Model B) Half-Height, SCSI model TC-L33CX-EY-B
• LTO-3 (Model B) Half-Height, SAS model TC-L33CN-EY-B
• LTO-4 (Model B) Half-Height, SCSI model TC-L43CX-EY-B
• LTO-4 (Model B) Half-Height, SAS model TC-L43CN-EY-B
• LTO-5 Half-Height, SAS model TC-L53CN-AR
• LTO-6 Half-Height, SAS model TC-L62AN-BR
• LTO-7 Half-Height, SAS model TC-L72AN-BR
• LTO-8 Half-Height, SAS model TC-L82AN-BR
You can upgrade a single-drive enclosure to the two-drive configuration by
installing a second tape drive using any supported model of the same type
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

2Connecting the Drive Interface and Power Cables
LTO-3, LTO-4, LTO-5, LTO-6, LTO-7 and LTO-8
Power Requirements Power requirements for the 1U Rackmount enclosure are as follows:
• 100 to 240 Volts AC, 2 to 4 Amps
• 47 to 63 Hz
Connecting the Drive Interface and Power Cables
1Shut down and turn off the host server system.
2Turn off all attached accessory devices, such as printers and other SCSI devices.
3On the back panel of a SCSI 1U Rackmount enclosure (see Figure 1):
Note: If this is a SAS 1U rackmount enclosure, continue with Step 4.
aConnect one end of the supplied external parallel SCSI cable to parallel SCSI
connector on the same side of the enclosure as the installed tape drive.
bConnect the other end of the supplied external parallel SCSI cable to the parallel
SCSI connector on the host server.
cAs required, use the parallel SCSI ID selector switch to set the SCSI ID of the
installed tape drive (see Figure 1).
Note: Any time you change the parallel SCSI ID, you must turn the tape drive
power off and then back on by pressing the power button on the front
panel of the 1U Rackmount enclosure.

4On the back panel of a serial-attached SCSI (SAS) 1U Rackmount enclosure (see
Figure 2):
aConnect one end of the supplied external SAS interface cable to one of the
external SAS interface connectors at the rear of the enclosure (see Figure 2). The
left-most SAS connector is for a drive installed on the left of the enclosure, and
the right-most SAS connector is for a drive installed on the right.

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.

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.

Installing the 1U Rackmount Enclosure in a Rack 15
LTO-3, LTO-4, LTO-5, LTO-6, LTO-7 and LTO-8
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 rack with threaded holes in the vertical
mounting bars you will need the following tool:
• 3/16 in. (5mm) flat-blade screwdriver
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.

LTO-3, LTO-4, LTO-5, LTO-6, LTO-7 and LTO-8
• 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.
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.
1Align the slotted holes on the left and right component rails with the three pins on
the sides of the rack mount enclosure.
2Slide the component rails toward the rear of the enclosure until they lock into place.

Note: To remove the component rail, pull out the spring-loaded tab on the side of the
rail and slide it forward.
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:
•Installing in a Rack with Round or Square Holes
•Installing in a Rack with 10-32 in. Threaded Holes
Installing in a Rack with Round or Square Holes
To install the 1U rack enclosure in a rack with round or square holes:
Note: The ends of the rack rails are marked FRONT and REAR for proper orientation.
1Insert the pins in the front mounting plate of the outer rack rails into the previously
marked holes in the front vertical mounting bars of the rack (see Figure 22). The rack
rails will lock securely into place.
