Production Note
This book was produced with the VAX DOCUMENT electronic
publishing system, a software tool developed and sold by Digital.
In this system, writers use an ASCII text editor to create source
files containing text and English-like code; this code labels
the structural elements of the document, such as chapters,
paragraphs, and tables. The VAX DOCUMENT software, which
runs on the VMS operating system, interprets the code to format
the text, generate a table of contents and index, and paginate the
entire document. Writers can print the document on the terminal
or line printer, or they can use Digital-supported devices, such
as the LNO3 laser printer and POSTSCRIPT printers (PrintServer
40 or LNO3R ScriptPrinter), to produce a typeset-quality copy
containing integrated graphics.

Using the DECsystem 3100

Using a Tape Drive
The optional TK50Z tape drive can store 95 megabytes on each of
its TK50-K (CompacTape) tape cartridges, or 296 megabytes on

each TK52-K (CompacTape II) tape cartridges. Its function is to
read and write data to and from the magnetic tape in a cartridge.

The cartridges for your tape drive contain magnetic tape
on a single reel. The top of each cartridge carries the label

“CompacTape.”
When you load a cartridge, the tape automatically threads onto

the reel inside the drive.

Before you remove a cartridge, the tape must be fully rewound.
This process can take up to 90 seconds. Rewinding occurs
automatically when you attempt to remove the cartridge.

Checking the Position of the Tape Leader Inside a
Cartridge
Before using a cartridge, check the position of the leader inside by

doing the following:

Remove the cartridge from its protective case.

Open the door on the back of the cartridge.
a

Insert your thumb into the groove on the right corner of
the back of the cartridge.

Press up on the door lock to release it.

Push the right edge of the door away from you until
the door is fully open and you can see the leader
(Figure 2-2).

How to use the self-test

What you can do to correct hardware problems and when to

ask for help
n

What kind of information your Digital service representative
needs from you

Important: In case you need to call your Digital service representative later,
you should write down the nature of the problem, including any
error messages you have received and the numbers of any self-tests
that fail. You should also list the steps you take to try to correct the
problem and the results you get.

Troubleshooting

4~1

Using the Self-Test
The self-test consists of a number of tests that check the parts
of your DECsystem 3100 and tell you whether they are working
correctly.
You can run the self-test in one of the following ways:
s

By turning on your system unit

By pressing the reset button on the back of the system unit
(see Figure 4-1)

By typing test -a at the console prompt (>>) and pressing
RETURN

Figure 4-1

The On/Off Switch and Reset Button on the System
Unit
Reset button

On/off switch

MLO-002803

When you turn the system unit on, the self-test starts
automatically. A self-test performed this way is called a power-up
self-test.

4-2

Troubleshooting

If the power-up self-test is successful, a display similar to the
following appears on your screen:
KNO1l

16Mb.......... 0
KNO1 V6.5

08-00-2b-0d-£f7-6a
0x01000000
>>

When you type test -a to run a self-test, the power to the
DECsystem 3100 is not turned off. Tests performed this way
are simply called self-tests.
If the self-test is successful, a display similar to the following
appears on your screen.

KNO1 V6.5
7..6..5..4..3..2..1..0
16Mb.......... 0
>>

If a Self-Test Fails
If your DECsystem 3100 fails one of its tests, self-testing stops

and a display similar to the following will appear on the screen:
KNO1

V6.5

7..6..5..4..3..2..
FAILURE

16Mb.......... 0
>>

The number of the test that failed is the last number that
appeared on your screen before the failure message.

Troubleshooting

4-3

If Test 7, 6, 5, or 4 Fails
Record the number of the test that failed and report it to your

system manager or to your Digital service representative.

If Test 2 Fails
Check your Ethernet connections.

DECsystem 3100 on Standard Ethernet Follow these steps for a
DECsystem 3100 on a standard Ethernet:

Turn your system unit off and make sure the standard
Ethernet cable connector is securely connected to the standard
Ethernet connector on the back of the system unit and that
the slide latch is engaged. See Figure 4-2.

Interpreting Self-Tests

This section tells you how to interpret the results of the following
types of self-tests:

Power-up self-tests and self-tests

Power-up self-test codes that appear in the LED status display
on the back of the system unit

Using the Power-Up Self-Tests and the Self-Tests
There are two ways to interpret self-test results when a test fails:
s

Use the test code number displayed on the console terminal.

Use the LED codes that appear on the LED status display on
the back of the system unit.

Test code numbers that display on the console terminal are
described in Table B—1. If a test fails the number of the test that
failed is the last number displayed on your screen.
Table B-2 describes codes that are represented when various
combinations of lights on the LED status display glow red on the
back of the system unit.
