Installation Instructions
201414- 002
The Compaq SDLT tape drive requires a Wide-Ultra SCSI
Controller or higher.
Step 1, Set the SCSI ID (Figure A)
Each SCSI device on the same SCSI bus must have a
unique SCSI ID. The default for Compaq tape drives is 6. If
needed, change the SCSI ID by pressing the button above
or below the number display on the back of the tape drive
enclosure.
IMPORTANT: SCSI ID 7 is reserved for the SCSI controller, two SCSI
controllers have IDs 6 and 7.
Step 2, Connect the Cables (Figure B)
1. Turn off the computer and any peripherals.
2. Attach the SCSI signal cable 1to the SCSI connector
2located on the rear panel of the SDLT drive and
then to the external SCSI-2 port on the computer. Use
the appropriate SCSI cable for your computer SCSI
connection. Two 6-ft (1.8-m) cables are provided.
3. Attach the terminator (not shown) to the SCSI
connector 3.

4. Plug the tape drive’s AC power cord 4into the drive
and then plug the other end into a grounded AC
outlet.
WARNING: To reduce the risk of electric shock or
damage to your equipment, do not disable the power
cord grounding feature. This equipment is designed
for connection to a grounded (earthed) power outlet.
The grounding plug is an important safety feature.
5. Turn on all peripheral devices and the computer.
Daisy Chaining - Optional Configuration (Figure C)
Two SDLT tape drives can be connected to the same SCSI
channel at the same time. Use a 6-ft (1.8-m) cable to attach
the initial unit, then use a 3-ft (0.9-m) cable to daisy chain
the additional tape drive.
IMPORTANT: Do not connect more than two tape drives per SCSI
controller. If using a low voltage differential (LVD) controller, more than
2 drives can be connected per controller. Refer to your LVD manual
for cable configurations.
1. If the first drive unit has a terminator on the SCSI
connector 1, remove it.
2. Connect the tape drives together by placing a SCSI
cable between the SCSI connector 2of the first drive
to the SCSI connector 3of the second drive.
3. Place the terminator (not shown) on the SCSI
connector 4of the second drive.
4. Turn on all peripheral devices and the computer.
Installation is complete. For more information about your
tape drive, refer to the Compaq SDLT Drive Reference
Guide that came with your tape drive.
