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.
Figure 1 Parallel SCSI Interface
Connectors
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.

5Connect the supplied AC power cable to the AC power connector on the back panel
of the 1U Rackmount enclosure (see Figure 3).
Figure 3 AC Power Connector
6Connect the other end of the AC power cable to the rack/facility AC power
receptacle.
7Press the drive power pushbutton switch on the front panel of the 1U Rackmount
enclosure, illuminating the power LED. (see Figure 4).

8Turn on all attached accessory devices, such as printers and other SCSI devices that
you turned off at step 2 of this procedure.
9Turn on and restart the host server.

4Installing a Second Tape Drive or Replacing a Tape Drive
LTO-3, LTO-4, LTO-5, LTO-6, LTO-7 and LTO-8
Installing a Second Tape Drive or Replacing a Tape Drive
Follow these instructions to install a second tape drive or to replace a tape drive after it
has been removed.
Caution: Before installing a second tape drive, you must turn off the 1U Rackmount
enclosure and disconnect it from its AC power source.
Preinstallation
Requirements
Before installing a second tape drive in the 1U Rackmount enclosure, make sure you
have the following required tools and parts:
Installation Procedure The installation procedure is divided into the following major sections:
•Removing the Top Panel
•Adding a Second Tape Drive
•Replacing a Tape Drive:
•Connecting the Tape Drive Cables
•Re-installing the Top Panel
Removing the Top Panel
To remove the top panel:
1Press the drive power pushbutton switch on the front panel of the 1U Rackmount
enclosure to turn off the drive power.
2Disconnect the AC power cable from the AC power connector on the back panel of
the 1U Rackmount enclosure.
3Remove the 1U Rackmount enclosure from the equipment rack and place it on a
clean, stable, flat surface.
4Remove the top access panel (see Figure 5):
aLoosen the latch screw
bLift the latch and slide the top panel toward the back of the 1U rackmount
enclosure.
