Place the TZ87 on a flat, sturdy, level area such as a desk or tabletop–not on
the floor.

1.3.2 Site Guidelines
Be sure to follow these guidelines for your TZ87:
•

Avoid a site that is dusty or humid.

•

Allow enough space around the TZ87 for ventilation and for easy access to
the front and rear.

1.4 Affix Decals
1.4.1 For Foreign Language Decals Only
If applicable, choose the foreign language decals with the language appropriate
for your country. Affix them over the English labels. (See the diagrams in
Section 1.4.3.)

2.2.1 TZ87 Factory Settings
The TZ87 is factory set to SCSI ID 5, the usual ID for tape devices on the SCSI
bus. If your system generates parity, the TZ87 can check for correct parity on
the SCSI bus.

2.2.2 Configuration Guidelines
Your system uses the SCSI ID to identify, or address, the TZ87. Follow these
guidelines when configuring the TZ87 for your system:
1. Verify that your drive has a unique SCSI ID from any other device on the
SCSI bus.
2. If your drive is the last device on the bus, you must install a terminator on
the drive—to terminate the bus.
Figure 2–1 shows the location of the DISABLE PARITY and SCSI ID
switchpack.

2.2.3 Disable Parity Checking
If your system does not generate parity, you must disable parity checking on
the TZ87. To do so, set the DISABLE PARITY switch to ON by pressing down
on the left side of the switch with a pen. (See Table 2–1 for switch 1.)
Caution
Never use a pencil to press the switches on the switchpack. Use only a
pen.

2.2.4 To Change the SCSI ID
If you need to change the SCSI ID, see Section 2.2.5 and:
•

If a setting is 1 (ON), make sure the left side of the switch is down.

•

If a setting is 0 (OFF or OPEN), make sure the right side of the switch is
down.

2.2.5 SCSI ID Switch Settings
Use the following table to determine SCSI ID switch settings. (See Table 2–1
for switches 2, 3, and 4.) Switch 2 is the most significant bit (MSB) and switch
4 is the least significant bit (LSB):

the TZ87 rear panel.
2. Snap the wire cable clamps into place to secure the cable.
3. Connect the other end of the SCSI signal cable to the SCSI connector on
your system or, for daisy-chained configurations, another SCSI device.
See your system documentation for system SCSI connections.

2.3.3 Terminate the SCSI Bus
If the TZ87 is the last or only device on the SCSI bus, follow these steps to
install the terminator:
1. Connect the SCSI terminator to the rightmost SCSI signal connector on the
TZ87 rear panel.
2. Snap the wire cable clamps into place to secure the terminator.
If the TZ87 is not the last or only device on the SCSI bus, be sure to install the
terminator at the end of the bus.

2.3.4 Connect the Power Cord
To connect the power cord, follow these steps:
1. Be sure the TZ87 power switch is set to 0.
2. Connect the power cord to the TZ87 power connector. Make sure the
connector is fully seated.
3. Connect the other end of the power cord to a nearby ac outlet.

Installation Testing
3.1 Overview
3.1.1 To Test the Installation
Perform these steps to test the installation:
Step

Action

Turn on system power.

Set the power switch on the TZ87 rear panel to on.
Result: The power-on self-test (POST) runs automatically when you turn on
the TZ87.

Observe the TZ87 front panel indicators.

Did POST succeed (Section 3.2.1)?

•

If yes, go to step 5.

•

If no, see Section 3.2.2.

Bring up the system and run the optional system tests.
Result: You are ready to operate the TZ87.

Installation Testing 3–1

Installation Testing
3.2 Run the Power-On Self-Test

3.2 Run the Power-On Self-Test
3.2.1 POST Success
When you turn on system power, the drive performs the POST. The sequence
of events follows:
Stage

What Happens

The lights on the right front panel turn on sequentially, from top to bottom.
All lights stay on for a few seconds.

All lights on the left side turn on at the same time for about three seconds
and then turn off.

The green Operate Handle, the orange Write Protected, and the yellow Use
Cleaning Tape lights turn off. The yellow Tape in Use light blinks while the
tape drive initializes.

After initialization, if no cartridge is loaded, the yellow Tape in Use light
turns off, the green Operate Handle light turns on, the handle unlatches,
and the beeper sounds.

POST completes in about 13 seconds and the subsystem responds normally to
all commands. However, it might take longer for the media to become ready.
After a bus reset, the tape drive responds within a bus selection timeout
period.

3.2.2 POST Failure
If all left- or right-side lights on the TZ87 front panel blink repeatedly, POST
did not run successfully. Follow these steps:
Step

Action

Make sure your cable connections are secure.

Make sure the SCSI bus is terminated correctly.

Power the TZ87 off and then on again to rerun POST.

If all front panel indicators blink again, you most likely have a hardware
failure. Call Digital Services at your local Customer Support Center.

3.3.1 System Startup
After successful completion of POST, have the system manager perform the
following steps:
Step

Action

Restart the operating system.

Configure the system to recognize the TZ87.

3.3.2 Other Tests
See your system documentation for instructions on running a full system or
SCSI bus test.

3.4 Ready To Operate
3.4.1 For Operating Instructions
Once you have verified a successful installation, see the TZ87 Cartridge Tape
Subsystem Owner’s Manual (EK–OTZ87–OM) for information on using the
TZ87.

Solving Problems
A.1 What to Do
A.1.1 Troubleshooting Chart
If the TZ87 fails during power-up or operation, use the following chart to
determine the problem and the action to take. If you cannot solve the problem,
call Digital Services at your local Customer Support Center.
If. . .

Then. . .

You should. . .

Your system does not
recognize the TZ87

Your system is not
configured to see the
SCSI ID

Configure your system to see the
ID. For example, use SYSGEN
AUTOCONFIG on the VMS
operating system.

The SCSI ID is not
unique

Change the SCSI ID and
reconfigure the system. New
ID effective at next power-on.

The parameters for
your SCSI adapter are
incorrect

Check your SCSI adapter
installation.

The SCSI signal cable is
loose

Make sure the connector on each
end of the cable is fully seated.

The SCSI terminator is
not present or is loose

Install the terminator; make
sure the terminator is fully
seated.

Solving Problems A–1

Solving Problems
A.1 What to Do
If. . .

Then. . .

You should. . .

The SCSI bus is not
correctly terminated

If the TZ87 is the last or only
device on the bus, make sure
the terminator is installed on
the TZ87.
If the TZ87 is not the last or
only device on the bus, check
the cable connections and make
sure the terminator is installed
at the end of the bus.

The SCSI terminator
is not at the end of the
bus, or more than two
terminators are present

Be sure to install a terminator
at each end of the bus. One
terminator is usually installed
at the system.

The SCSI bus is too
long, or too many
devices are on the bus

Limit the bus length to the
ANSI SCSI standard of 6 meters
(19 feet) and the number of
devices on the bus (including
the system) to eight. Check your
system configuration rules.

The TZ87 does not
power up

The TZ87 has no power

Check the TZ87 power cord
connections, with the TZ87
power switch off.

All right or left side
lights on the TZ87 front
panel blink

A drive fault has
occurred

Press the Unload button on the
TZ87 front panel or turn drive
power off and then on again to
clear the error. If the error does
not clear, call Digital Services.

You are finding fatal or
nonfatal errors for which
you cannot determine
the cause

The bus termination
or SCSI signal cable
connections may be
incorrect

Make sure the SCSI bus is
terminated.

The ac power source
grounding may be
incorrect

Use an ac outlet for the TZ87
on the same ac line that is
powering the system.
