1Introduction
The LTO-2 Half-Height Tape Drive is a high-performance 8-channel tape
drive that complies with the LTO interchange specifications. It is suited
for mid-range to high-end servers, mainframe systems, and tape library
automation systems.
The LTO-2 Half-Height Tape Drive uses Ultrium data cartridges. Its
capacity is maximized using intelligent data compression. The drive has a
native capacity of 200 Gbytes (400 Gbytes assuming 2:1 data
compression).
Figure 1 Drive

Unpacking and Inspection
Unpacking and Inspection 2
Although drives are inspected and carefully packaged at the factory,
damage may occur during shipping. Follow these steps to unpack the
drive.
1 Visually inspect the shipping containers and notify your carrier
immediately of any damage.
2 Place shipping containers on a flat, clean, stable surface; then
carefully remove the contents. If the equipment is damaged, notify
your Quantum representative.
3 Always save the containers and packing materials for any future
reshipment.
Internal Tape Drive Guidelines and Cautions 2
The following guidelines and cautions apply to handling and installing
internal tape drives. Keep them in mind as you install the drive.
• Handle the drive by the sides rather than by the top cover to reduce
the risk of dropping the drive or damaging it during installation.
• Internal drives contain some exposed components that are sensitive
to static electricity. To reduce the possibility of damage from static
discharge, the drives are shipped in a protective antistatic bag. Do not
remove the drive from the antistatic bag until you are ready to install
it.
• Before you remove the drive from the antistatic bag, touch a metal or
grounded surface to discharge any static electricity buildup from
your body.
• Always lay the drive either on top of the antistatic bag or place it
inside of the bag to reduce the chance of damage from static
discharge.
• Install LVD drives only in an LVD environment. Do not mix LVD and
HVD devices on the same SCSI bus.
6 LTO-2 Half-Height Tape Drive User’s Guide
Chapter 2 Installation and Quick Start
Drive Installation Instructions
• Due to the speed of the LTO-2 Half-Height Tape Drive, it is
recommended that a maximum of one LTO-2 drive be connected to
one channel on a host SCSI adapter.
Drive Installation Instructions 2
After unpacking and inspecting your shipping containers and reviewing
the installation guidelines and cautions, proceed to the appropriate
section in this chapter for instructions on installing your internal or
desktop LTO-2 Half- Height Tape Drive.

Configuring the Internal Tape Drive
Before you install the LTO-2 Half-Height Tape Drive in your computer,
you may need to configure the drive’s SCSI ID and terminator power
2
features. The default configuration settings for the LTO-2 Half-Height
Tape Drive are:
LTO-2 Half-Height Tape Drive User’s Guide 7
Chapter 2 Installation and Quick Start
Installing an Internal LTO-2 Half-Height Tape Drive
• SCSI ID: 6
• Terminator power: disabled
If you need to change these settings, refer to the following sections.
Otherwise, skip to Mounting the Internal Tape Drive
on page 11.
SCSI ID
• Jumper Pins: 1–2, 3–4, 5–6, 7–8
• Default Setting: SCSI ID 6
Each SCSI device on the bus must have its own unique SCSI ID. The
internal tape drive is shipped with a default SCSI ID of 6. If another SCSI
device in the SCSI chain is using this ID, use jumper pins 1–2, 3–4, 5–6,
and 7–8 to change the SCSI ID of the LTO-2 Half-Height Tape Drive (see
figure 2
and table 1), or assign a unique SCSI ID to the other SCSI device.
Note: The SCSI controller or host adapter generally uses ID 7. In
some systems, the boot drive uses ID 0 or ID 1. Avoid setting
your drive’s SCSI ID to these settings.

Terminator Power 2
By default, terminator power is disabled on the internal LTO-2
Half-Height Tape Drive. To enable terminator power, place a jumper
across pins 11 and 12.
Note: The internal LTO-2 Half-Height Tape Drive does not provide
SCSI termination. Thus, a terminator must be installed on the
drive if it is the last device in a SCSI chain.

Mounting Orientation
You can mount the internal LTO-2 Half-Height Tape Drive either
horizontally or vertically (see figure 3

).
• If you mount the drive vertically, the side of the drive should be
within 5 degrees of horizontal.
• If you mount the drive horizontally, the base of the drive must be
within 15 degrees of horizontal and the drive must be right-side up.
YES NOYES YES
Mount the drive in a 5.25-inch, half-height drive bay and secure it using
two M3.0 X 3 metric screws on each side of the drive.
Caution: Do not use screws longer than 3 mm or you may damage
the drive. Figure 4
shows the locations of the mountingscrew holes on the side and bottom of the drive,
respectively.

The internal LTO-2 Half-Height Tape Drive has an Ultra3 SCSI interface,
terminated by an LVD SCSI connector. Use the following procedure to
2
connect a SCSI cable to this connector.
1 Turn off all power to the drive and the computer.
2 Attach the SCSI interface cable to the 68-pin SCSI interface connector
on the back of the drive (see figure 5
).

By default, the internal LTO-2 Half-Height Tape Drive does not provide
SCSI termination. If you use this default setting, you must place a SCSI
2
bus terminator or a SCSI device with termination enabled at the end of
the SCSI chain. See figure 6
for two examples of SCSI termination.
The internal LTO-2 Half-Height Tape Drive provides terminator power if
a jumper is placed on the termination power jumper pins (see Terminator
Power on page 10).

Connecting a Serial Cable for Tape Libraries
The Internal LTO-2 Half-Height Tape Drive include an RS-422 serial

Installing the LTO Driver
Registering Your Tape Drive
If you intend to use your drive with the Microsoft native backup applet
on Windows Server 2003, Windows XP, or Microsoft Windows 2000
2
operating system, install the appropriate LTO driver. See the Resource
CD. This driver is not necessary with commercial backup application
software.
After you install the internal tape drive, be sure to register it. Registering
your drive ensures that you will receive the latest information about your
2
drive, as well as other product, service, and support information. For
your convenience, you can register your drive through our Web site at:
