 
3UHSDUDWLRQ
Use these instructions to install your Exabyte 8mm half-high
tape drive.
Note: If you have an Exabyte Mammoth 8mm tape drive,
order Quick Installation–Exabyte Mammoth 8mm Tape
Drives (321410) from Exabyte, or refer to Exabyte’s
World Wide Web site (www.exabyte.com).
These instructions assume that you are installing the tape
drive in a computer drive bay. If you are installing the tape
drive in a library or other enclosure, you will need to adapt
the instructions to your specific situation.
Before you begin, read through the instructions to determine
what you will need. Depending on your setup and existing
equipment, you may need to obtain the following items:
wSmall flat-nose pliers, flat-blade and Phillips screwdrivers
wSCSI adapter card (must be installed in your computer)
wSCSI ID jumpers
wTerminators
wSCSI cable
wDrive bay mounting rails
All of these items (except tools) are available from Exabyte.
Call 1-800-EXATAPE (1-800-392-8273).

Protect the tape drive from electrostatic discharge (ESD) by
following these precautions: Use an antistatic mat and
wristband, if possible. Leave the tape drive in its packaging
until you are ready to install it. Touch a known grounded
surface (such as a metal table) before handling the tape drive.

1. Remove your computer's cover.
2. Remove the coverplate from the drive bayyou intendto
use. Save any screws or clips you remove.
Note: You may need toremove a device,such asan extra
floppy disk drive, to provide a drive bay for the
tape drive. Do not remove your floppy drive A. If
you remove a device, be sure to modify your
system configuration to reflect the change.
3. Determine whether the tape drive needs rails for
mounting in the drive bay. If devices in other drive bays
use rails, or if the tape drive fits loosely, you should use
rails. You can obtain rails from a computer supplier or
from Exabyte. If necessary, install the rails as follows:
Using the screws provided with the rails, fasten a rail to
each sideofthetapedrive. Usewhicheversetofmounting
holes allows the front of the tape drive to be even with
devices in other drive bays. (You may want to leave the
screws holding the rails loose until you have determined
the exact position of the tape drive.)

The tape drive attaches to a SCSI bus, which consists of the
SCSI adapter cardin your computer, one or more SCSI cables,
and up to eight SCSI devices (including the adapter card).
Each device on the bus must have its own SCSI ID.
To set the SCSI ID, use a pair of flat-nose pliers to position the
jumpers on the SCSI ID jumper block on the back of the tape
drive, as shown below. (Depending on your model, the
jumper block may be in a different location.)
CAUTION
Turn off all devices attached to your computer,
then turn off the computer. Disconnect all power
cablesfrom yourcomputerandattached devices.
CAUTION
To avoid damaging the tape drive, use only the
screws provided with the rails.

 
Note: If you are using a remote switch to set the SCSI ID,
remove the jumpers fromthe jumperblockand attach
the switch connector. Make sure that the switch is no
more than 30.5 cm (12 inches) from the jumper block.

The devicesat each end ofa SCSIbus must beterminated. The
SCSI adapter card is typically at one end of the bus and has its
own terminators. If the tape drive will be located at the other
end of the bus, it must be terminated also.
The method for termination depends on whether your tape
drive has a single-ended or differential SCSI configuration.
6LQJOHHQGHGWDSHGULYH
Most single-ended models use three resistor terminators
(R-packs) for termination. Others use external terminators.
Check for the R-packs just above the SCSI connector on the
back of the tape drive, as shown below.
If the tape drive uses R-packs: Make sure the R-packs are
installed if the tape drive is at the end of the SCSI bus. If you
need to install R-packs, make sure that pin 1 of each R-pack is
aligned with pin 1 of the socket and that no pins are bent. If
the tape drive is not at the end of the SCSI bus, use a pair of
flat-noseplierstocarefullygraspeachR-packatthecenterand
pull it straight out.
If the tape drive does not use R-packs: Install an external
pass-through terminator on the SCSI connector if the tape
drive is at the end of the SCSI bus. External terminators are
available from Exabyte.
'LIIHUHQWLDOWDSHGULYH
If you need to terminate a differential tape drive, install an
external pass-through terminator on the tape drive’s SCSI
connector. External terminators are available from Exabyte.

The method you use toconnect the tape drive to the SCSI bus
depends on whether the tape drive is the only device on the
bus or you have other devices on the bus.

1. Ifitisnotalreadyconnected,connecttheSCSIcabletothe
SCSI adapter card, and thread the cable out through the
front of the open drive bay.
2. Attach the SCSI cable to the tape drive's SCSI connector.
If the cable connector is not keyed, make sure that the
colored stripe on the cable (indicating pin 1) corresponds
to pin 1 of the tape drive’s SCSI connector (on the right
side as you look at the back of the tape drive).
3. Making sure that no cables are in the way, carefully slide
the tape drive into the bay.

1. Make sure that the devices at each end of the bus are
terminated correctly. These instructions assume that the
tape drive is not at the end of the bus and is therefore not
terminated.
2. Ifit is not already connected, connect one end of the SCSI
cable to the SCSI adapter card and the other end to the
device that terminates the SCSI bus.
3. Making sure that no cables are in the way, carefully slide
the tape drive into the bay.

4. Connect an available connector on the SCSI cable to the
tape drive’s SCSI connector. Make sure that the colored
stripe on the cable (indicating pin 1) corresponds to pin 1
of the tape drive’sconnector (on the right side asyou look
at the back of the tape drive).
5. If not already connected, connect your other SCSI devices
to available connectors on the cable.

1. Locate a free power cable from your computer's power
supply. Push the keyed connector ➊into the tape drive's
power connector.
2. If your computer uses a grounding wire for additional
grounding of internal devices, locate the wire. Use a
1/4-inch female spade connector ➋to attach the wire to
the grounding tab on the back of the tape drive. Or, use
an M3-0.5 x 6 mm self-tapping screw ➌to attach the wire
to the grounding hole. (Depending on your model, the
grounding tab and hole may be in different locations.)
3. Secure the tape driveto the drive bayasinstructedin your
computer manual. You may need to use the clips or
screws from the drive bay's cover plate. Make sure that
the front of the tape drive is even with devices in other
drive bays. (If you used mounting rails, adjust their
position as necessary and tighten the rail screws.)
4. Replace the computer’s cover.
5. Reconnect the power cords to your computer and all
attached devices. Turn on the computer and devices.
6. Wait about 30 seconds while the tape drive performs its
power-on self-test. When the self-testiscomplete,the top
and bottom LEDs turn off. The middle LED will be off or
flashing irregularly. If the top LED does not go out after
the self-test, contact your vendor for assistance.

✔Make sure that the SCSI adapter card and all SCSI
connectors are completely seated.
✔Make sure that the SCSI bus is terminated correctly.
✔Verify that the total length of all SCSI cables on the bus
does not exceed 6 meters (19.7 feet) for a single-ended
configuration or 25 meters (82 feet) for a differential
configuration.
✔Verify that the tape drive’s SCSI ID is not the same asthe
ID used by any other device on the bus.
✔Verify that all devices on the SCSI bus are either
single-ended or differential. Do not mix the two types.
✔Check your SCSI adapter card documentation to make
sure that you have set all jumpers and switches correctly.
