Installing the Drive
Follow these instructions to install your tape drive:
1. All devices attached to a SCSI adapter must have a unique SCSI
identification number (ID). Select a SCSI ID for the tape drive in
the range of 0 to 6. The SCSI ID must be one that is supported
by your SCSI host adapter. The tape drive is shipped with the
SCSI ID preset to 0. Do not assign an ID of 7 because this is
normally used for the SCSI host adapter.
2. Turn off all attached devices. Turn off the computer. Unplug the
1GB equals one billion bytes when referring to storage capacity.

power cords for the computer and all attached devices; then open
the computer.
3. Before opening the static-protective bag containing the tape drive,
touch the bag to an unpainted metal surface on the computer for
at least two seconds. This will drain any accumulated static
electricity from the bag and your body. Remove the drive from
the static-protective bag. If you must put the drive down, place
the drive on the static-protective bag. Do not touch any exposed
components on the drive.
To install the drive, refer to the following drive backpanel

Part 1: Quick Installation Guide 1-3

When you connect SCSI drives to the SCSI adapter, start with the
SCSI connector on the cable that is farthest from the adapter.
Then, with each additional device, work your way in from the far
end back towards the adapter. Connecting the devices in this
order ensures the best possible signal quality. Connect the SCSI
and power cables to the tape drive connectors. Ensure that pin 1
of the SCSI cable aligns with pin 1 of the SCSI connector. Pin 1
is usually a different color than the other pins so that it can be
easily identified. If your SCSI cable is a different size than the
connector on your tape drive, use the converter that is included in
the option package. For more information, see “Step 5.
Connecting Cables and Terminating the Chain” on page 2-6.
8. If the tape drive is the last device on the SCSI chain, the chain
must be terminated at the drive. To terminate the SCSI chain,
you must set the Active Termination Enabled jumper to ON. To
locate the Active Termination Enabled jumper, refer to the
illustration on page 1-2. There is also an illustration on page 1-2
which shows how to set jumpers to ON or OFF.
9. Replace the computer cover and secure it in place. Reconnect the
power cord and any other signal cables. Turn on all attached
devices; then turn on the computer. Ensure that the appropriate
advanced SCSI programming interface (ASPI) device drivers are
installed to support the tape drive. These device drivers are
usually provided with the SCSI adapter. You might need to
reconfigure your SCSI adapter. See the documentation that
comes with your computer or adapter.
10. After the power is turned on, or after any power reset, the tape
drive performs a power-on self test. This is indicated by both
LEDs blinking for about 5 seconds. It is important to make sure
the drive is empty during the self-test. Do not try to insert a
cartridge into the tape drive during the self-test.
11. Install your backup and restore software. Follow the installation
and operating instructions included with your software to begin
using the tape drive. For more information, see “Backup and
Restore Server Software” on page 2-2.
12. If your computer does not recognize your tape drive during the
computer’s power-on self test (POST) or if you receive startup
errors, run the configuration-setup utility program as described in
the documentation that comes with your computer.

Installing the Drive
Follow these steps to install the tape drive.
Step 1. Selecting a SCSI ID
Each device on a SCSI bus must have its own SCSI ID. You can
select a SCSI ID for the tape drive in the range of 0 to 7. The SCSI
ID must be one that is supported by your SCSI host adapter. Refer to
your SCSI host adapter documentation for the range of and the relative
priority of the IDs supported. The tape drive is shipped with the SCSI
ID preset to 0.
Follow these guidelines to select a SCSI ID:
Assign the tape drive to the lowest priority ID available.
Assign the higher-priority ID numbers to those devices that are
most often used or are faster than other devices in the chain.
Do not assign an ID of 7 because this is normally the highest
priority ID and it is used for the SCSI host adapter.
If you are installing the tape drive in a RAID storage enclosure,
the lowest SCSI IDs might be reserved for hard disk drives.
Assign the tape drive to the lowest available SCSI ID.
Depending on your computer, there are several ways to view your
current SCSI ID setting:
For most IBM computers, press F1 during the startup, after the
memory check completes.
Use your SCSI adapter’s utility programs, if available.
Inspect the installed SCSI devices to see how the IDs are set.
For more information, refer to the documentation that comes with your
computer or SCSI bus adapter.
Step 2. Preparing for Installation
Refer to the drive backpanel illustration during installation.
The tape drive components are:
.1/ SCSI connector
.2/ Jumper block
.3/ Power connector
To prepare for installation:
1. Turn off all attached devices. Turn off the computer. Unplug the
power cords for the computer and all attached devices; then open
the computer. For specific information on opening your computer
refer to the documentation that comes with your computer.
Attention: Tape drives are sensitive to static electricity discharge.
The drives are wrapped in a static-protective bag to prevent damage.
Part 2: User's Guide 2-3

2. Before opening the static-protective bag containing the tape drive,
touch the bag to an unpainted metal surface on the computer for
at least two seconds. Make sure to touch a metal surface before
touching the drive, to ground any accumulated static energy.
Remove the drive from the static-protective bag. If you must put
the drive down, place the drive on the static-protective bag.
Step 3. Setting the SCSI ID
Use the jumper block, .2/ in the back panel illustration on page 2-3,
to set your SCSI ID. To set your jumpers, refer to the following
illustrations. Remove and position jumpers to obtain the ID. If
necessary, use a pair of flat-nose pliers to remove the jumpers. The
following illustration shows the ON and OFF positions for jumpers.

Step 4. Mounting the Drive
Mount the tape drive and then firmly attach the signal and power
cables to it. If there is insufficient working space to attach the
connectors after mounting the drive, attach the cables first. To mount
the drive:
1. Locate an available bay or space in your computer to mount the
tape drive. The drive can be mounted in either a horizontal or
vertical position. Remove the cover plate from the bay selected.
2. The drive housing has two sets of four mounting holes .1/ .2/
to provide a number of mounting positions. Use one of the two
sets of mounting holes that provides the best fit and mounts the
drives securely. The illustration shows the pairs of hole on only
one side of the drive.
3. Align the drive-bay screw holes with the threaded holes in the
drive housing. When mounting the tape drive, follow these
guidelines:
Use only one set of mounting holes.
Use all four holes in whichever set you choose; do not use
combinations of mounting holes from different sets.
Ensure that no objects such as screw heads, cables, or
adjacent devices are pressing against the frame.
Ensure no obstruction blocks the ventilation slots on the
bottom and at the rear of the tape drive.
Part 2: User's Guide 2-5

Step 5. Connecting Cables and Terminating the Chain
To attach the SCSI and power cables to the tape drive:
1. Locate the SCSI bus cable (often a 68-pin ribbon cable). One
end of the cable connects to the SCSI host adapter that can be on
the computer system board or an adapter installed in an expansion
slot. The other end can have several connectors for attaching
devices.
2. Locate an available SCSI connector at the opposite end of the bus
cable from the SCSI host adapter. Use all empty bus connectors
at the end farthest from the adapter first to ensure better signal
quality. Attach the SCSI bus cable to the tape drive. The tape
drive has a 50-pin connector. If your SCSI cable has a 68-pin
connector, use the included 68-pin to 50-pin converter. Connect
the cable to the 68-pin side of the converter and connect the
converter to the tape drive Ensure that pin 1 of the SCSI cable
aligns with pin 1 of the SCSI connector. Pin 1 is often a
different color than the other pins to make it easier to identify.
3. The following example shows a bus cable with two devices on it.
The last device.1/on a bus cable must terminate the device chain.
1
If the tape drive is the last device on the SCSI chain, the chain
must be terminated at the drive.
To terminate the SCSI chain, set the “Active Termination
Enabled” jumper (pins 11-12) to ON. For more information, refer
to the illustrations on page 2-4.
If you install the device in an external storage enclosure and the
device is at the end of the SCSI chain, refer to your enclosure
documentation on termination. The enclosure might have a
terminator on a connector outside the enclosure.
Attention: Do not force the power cable into the tape drive power
connector. If the power cable is upside down and you force the
connection, you might damage the drive.
4. Connect the power cable connector to the four-pin connector on
the tape drive. If all the power cables are in use, purchase a
power-splitting cable at your computer dealer.
2-6 12/24 GB DDS/3 4 mm Internal Tape Drive

Step 6. Completing the Installation
Check your work before closing the computer.
1. Be sure that the power and interface connectors are securely
attached. Be sure that the cables are neatly routed. Be sure that
the air vents to the power supply are not blocked.
2. Replace the computer cover and secure it in place. Reconnect the
power cords and cables.
3. Turn on all attached devices; then turn on the computer.
Ensure that the appropriate Advanced SCSI Programming
Interface (ASPI) drivers are installed to support the tape drive.
Drivers should be provided with the SCSI host adapter.
Step 7. Updating the Configuration
For many computers, the power-on self-test (POST) and the
configuration-setup utility program automatically recognize the new
tape drive. However, you might have to answer questions about your
system changes when you restart (boot) your computer.
If your host computer does not recognize the tape drive after startup or
you receive startup errors, run the configuration-setup utility program
as described in the documentation that comes with your computer.
Step 8. Installing Backup and Restore Software
Install your backup and restore tape software. See “Backup and
Restore Server Software” on page 2-2 for more information. Follow
the installation and operating instructions included with your software
to begin using the tape drive.
