Unpacking and Handling the tape drive
The tape drive’s packaging is designed to protect the tape
drive from shock, vibration, moisture, and electrostatic
discharge (ESD). Save all original packaging in case you
need to repack or ship the tape drive.
If the temperature of the room in which you are unpacking
the tape drive varies from the storage location by 15°C(27°
F) or more, let the tape drive acclimate in its packaging to
the unpacking environment for at least 12 hours before
opening the box.
After you unpack the tape drive, check the contents of the
carton against the packing list and inspect the tape drive for
possible damage. If a part is missing or the tape drive is
damaged, notify the carrier and your vendor immediately.
Note: If the tape drive has been stored for more than six
months, follow the instructions on page 18 when
applying power for the first time. (Check the
MLCH label on the top of the tape drive to find
out when the tape drive was manufactured.)
CAUTION
Follow these procedures to protect the tape drive
from electrostatic discharge:
■Leave the tape drive in its antistatic bag until you
are ready to install it.
■Use an antistatic mat and grounded static
protection wristband. If a mat and wristband are
unavailable, discharge static electricity from your
body before handling the tape drive. (Touch a
known grounded surface, such as your
computer’s metal chassis.)
■If you must lay the tape drive down, place it into
or on top of the antistatic bag.
8EXB-8205 and EXB-8505 (Standard and XL) 302967

Setting the SCSI ID
After you have unpacked the tape drive, you can set the tape
drive’s SCSI ID. You can use either of the following methods:
■Attach jumpers (shunts) to the pins on the tape
drive’s SCSI ID jumper block. Jumpers are already
installed on the jumper block when the tape drive is
shipped.
■Connect a remote switch to the SCSI ID jumper block
on the back of the tape drive.
Setting the SCSI ID with Jumpers
To set the SCSI ID using jumpers, follow these steps:
1. Locate the SCSI ID jumper block on the back of the
tape drive, as shown in Figure 1.
2. Remove the jumpers from the jumper block to
obtain the correct address for your configuration.
Figure 2 shows how to position the jumpers for
addresses 0 through 7.
Figure 1 SCSI ID jumper block on the back of the tape
drive
May 1994 EXB-8205 and EXB-8505 (Standard and XL) 9

Setting the SCSI ID with a Remote Switch
If you want to set the SCSI ID remotely, you can attach a
remote switch assembly (not provided with the tape drive)
to the tape drive’s SCSI ID jumper block. To set the SCSI ID
with a remote switch, follow these steps:
1. Locate the SCSI ID jumper block on the back of the
tape drive, as shown in Figure 1.
2. If necessary, remove the jumpers from the pins.
3. Connect a remote switch to the jumper block.
Ensurethattheremoteswitchisnomorethan
30.5 cm (12 inches) from the jumper block.
4. Change the settings on the remote switch to the
correct address for your configuration. The switch
settings should emulate the jumper positions
shown in
Figure 2.
Note: For specific information about pin assignments
for the SCSI ID jumper block, refer to the
EXB-8205 and EXB-8505 Product Specification for
thetapedrive.

Preparing the Tape Drive for the SCSI Bus
The SCSI bus that you attach the tape drive to must be
terminated correctly to ensure proper operation. The devices
that are physically located at each end of the SCSI cable must
have terminators installed. All other devices on the SCSI
cable must not have terminators installed.
IfyouplacethetapedriveattheendoftheSCSIbus,you
must terminate the tape drive. The procedure you use
depends on whether the tape drive uses a single-ended or a
differential SCSI configuration.
Termination for a Single-Ended tape drive
The single-ended tape drive includes three single in-line
package (SIP) resistor terminators (R-packs) that can be left
in place if the tape drive terminates the SCSI bus.
CAUTION
The R-packs must be removed if the tape drive does
not terminate the SCSI bus or if external SCSI bus
termination will be used. Instructions for removing
the R-packs are provided below.
Optional External Termination
If desired, you can terminate the single-ended tape drive
externally by removing the R-packs from the back of the
tape drive and installing an external terminator. Exabyte
recommends a Methode Electronics, Inc. dataMate
DM103-02-0 single-ended external terminator.
Removing the R-Packs
To remove the R-packs, follow these steps:
1. Locate the three R-packs on the back of the tape
drive, as shown in Figure 3.
2. Using a pair of flat-nose wiring pliers, grasp each
R-pack in the center and pull it straight out. Be
careful not to squeeze the pliers too tightly or you
may break the R-pack.
May 1994 EXB-8205 and EXB-8505 (Standard and XL) 11

Replacing the R-Packs
If you need to put the R-packs back in the tape drive, make
sure that pin 1 of each R-pack is aligned with pin 1 of the
socket and that no pins are bent. As shown in Figure 3, the
writing on the R-pack should face upward. Pin 1 of the
R-pack is marked with a colored line or dot and should line
up with the right side of the socket.
CAUTION
If you replace an R-pack, be sure to use the correct
type to avoid damaging the tape drive. Use an
8-pin, 6-resistor SIP terminator, rated at 220/330
ohms. Exabyte recommends either of the following
terminators (or equivalent):
■Dale®: part number CSC 08A-05-221/331J
■Beckman Industrial™: part number
L08-5C221/331J
Termination for a Differential tape drive
The differential tape drive does not include internal
terminators. If a differential tape drive terminates the SCSI
bus, it must be terminated externally. See page 7 for
information about the recommended terminator.

(single-ended configuration)
12 EXB-8205 and EXB-8505 (Standard and XL) 302967

Connecting the SCSI Cable
After removing or installing terminators as required, connect
the SCSI cable to the SCSI connector on the back of the tape
drive. The connector is keyed so that it can be connected
only one way.
Figure 4 shows the location of the SCSI connector. See
Appendix A starting on page 36 for information about the
requirements for the SCSI cable.
Installing the Tape Drive in a Computer
If you are installing the tape drive in a drive bay in a
computer system, follow the guidelines in this section.
Otherwise, refer to Appendix A for general installation
requirements. Then, turn to page 18 to perform the initial
power on.
Preparing the Computer System
Before installing the tape drive in your computer system,
prepare the system as follows:
1. Turn off the computer and any attached devices.
2. Unplug the computer’s power cord.
3. Remove the computer’s cover as described in your
computer system documentation.
Figure 4 Location of SCSI connector
May 1994 EXB-8205 and EXB-8505 (Standard and XL) 13

4. If there is a cover plate over the drive bay you plan
to use, remove it. Refer to your computer system
documentation for instructions. Keep any screws or
mounting clips; you may need them to secure the
tape drive to the drive bay.
Note: If necessary, remove a floppy disk drive to
provide an empty half-high drive bay for the
tape drive. Refer to your computer system
documentation for instructions. Do not
replaceyourfloppydriveAwiththetape
drive.
Important
If you remove a floppy disk drive to install the tape
drive, be sure to change your system configuration
filestoreflectthechange.Refertoyourcomputer
system documentation for instructions.
Installation Procedure
Follow these steps to install the tape drive in the drive bay:
1. Check for the presence of a load resistor in your
computer. If it is present, disconnect the load
resistor cable from the power supply. Refer to your
computer system documentation for more
information.
2. Use #6 32 screws to attach two slide rails to the
sides of the tape drive as shown in Figure 5. You
can use rails that are provided with your computer
system or purchase rails from Exabyte or your
computer supplier.
Note: If there is more than one set of mounting
holes in the rails, use whichever set allows
you to position the tape drive flush with the
front of the drive bay.

5. Slide the tape drive into the drive bay and secure
the drive to the bay as instructed in you computer
system documentation.
6. If you needed additional chassis grounding,
connect a 1⁄4-inch female spade connector to the
ground tab at the rear of the tape drive. Or, connect
an M3-0.5 6 mm self-tapping screw to the
grounding hole. The ground tab and grounding
hole are shown in Figure 7.
Note: The power supply returns are connected to
the chassis, so you cannot isolate logic
common ground from chassis ground.

7. Locatethepowerconnectoronthebackofthetape
drive. Connect the power cable to the power
connector as shown in Figure 8.
CAUTION
The power cable plug and the power connector are
keyed so they can fit together in only one way.
Before connecting the plug to the tape drive, be
sure that the beveled edges of the plug are oriented
in the same way as the beveled edges on the power
connector. Do not force the plug into the connector
or you may damage the tape drive.
8. Replace the cover on your computer.

Performing the Initial Power On
The procedure you use to perform the initial power on
depends on how long the tape drive has been stored. If you
are not sure how long the tape drive has been stored, check
the MLCH (machine level control history) label on the top of
the tape drive to find out when the tape drive was
manufactured. Although the tape drive may have been
operated since it was manufactured, for the purpose of the
initial power on, assume that it has been stored throughout
this period.
Tape Drive Stored for Less Than Six Months
If the tape drive has been stored for less than six months, the
only step you need to perform for the initial power-on is to
apply power to the tape drive.
When power is applied, the tape drive performs its
power-on initialization and self-test (POST). Assuming that
no data cartridge is loaded and that the tape drive is
connected correctly, POST takes about 32 seconds, as follows:
■During the first part of POST, all three LEDs are lit.
■During the second part of POST, the top LED is lit
and the middle and bottom LEDs may flash,
depending on whether the tape drive is connected to
the SCSI bus and a data cartridge is loaded.
When POST completes (top LED off), the tape drive is ready
for normal operation.
Important
■Do not insert a data cartridge into the tape drive
while POST is occurring. The tape drive will eject it.
■If the top LED does not go out after POST, an
error has occurred. Contact your vendor.
18 EXB-8205 and EXB-8505 (Standard and XL) 302967

Tape Drive Stored for Six Months or More
If the tape drive has been stored for six months or more,
perform the following steps using your backup software to
ensure that the tape drive’s internal lubrication is properly
distributed:
1. Apply power to the tape drive. The tape drive
performs its POST as described on page 18.
2. Locate a test tape and ensure that the write-protect
switch is set to permit data to be written to the tape
(see page 25).
3. Insert the data cartridge into the tape drive with the
labelsideupandthewrite-protectswitchfacing
you.
4. Waitwhilethetapedriveloadsthetapeand
positions it to the logical beginning of tape (LBOT).
This takes about 40 seconds. When the bottom LED
is on solid, the tape drive is ready.
5. Perform a backup operation to write approximately
500 MB of data to the tape.
6. Rewind the tape and read the data written in step 5.
7. Repeat steps 5 and 6 at least two times or for two
hours (whichever is greater).
Note: If errors occur, reset the tape drive and
repeat steps 5 though 7 as appropriate.
When you have completed step 7, the tape drive is ready for
normal operation.
