Testing

This chapter provides an overview of the testing procedures for the

VAXstation 3100 Model 76 system. Since the testing procedures for the

VAXstation 3100 Model 76 are similar to the testing procedures for

the previous VAXstation 3100 models, this chapter will not repeat the

information described in Chapter 1 of the VAXstation 3100 Maintenance

Guide. If you are not familiar with the diagnostics available on the

VAXstation 3100 Model 76 system, you should read through the testing

procedures in Chapter 1 of the VAXstation 3100 Maintenance Guide. Also

refer to the WS01X-GA/GB Graphics Coprocessor Maintenance Guide.

The label on the back of the system box indicates which model you are

working on. The VS43A-xx model number on the label identiﬁes the

VAXstation 3100 Model 76 system.

All testing is performed while in the console mode and diagnostic tests

are ROM-based.

This chapter contains an overview of the following procedures:

• Running power-up tests

• Running self-tests

• Running system exerciser diagnostics

CAUTION

Do not remove or unplug the keyboard, mouse, printer, or

terminator without turning the power OFF. If the system is up

and running, use the proper shutdown procedure prior to halting

the system.
