Testing
This chapter describes how to test the VAXstation 3100 (VS 3100) model 30
and model
40
systems. Testing procedures on both models are similar and any
differences between them are specifically identified in the text. The label on
the back of the system box indicates which model you are working on. The
VS42A-xx model number on the label identifies the model 30 system and the
VS42S-xx model number identifies the model 40 system.
All testing is done while in console mode and diagnostic tests are ROM-based.
This chapter contains the following sections:
• Using
~onsole
mode
• Running power-up testing
• Running self-tests
• Running system exerciser diagnostics
1.1 Using Console Mode
The VS 3100 system has two modes of operation: program mode and console
mode. Program mode is when the operating system (for example, VMS or
ULTRIX) is controlling the system. Console mode allows the user to control
the system from the console terminal using the console commands described
in Appendix B. Console mode is contained in ROM on the system module.
Testing is done while in console mode. The system returns the console prompt
>>>when it is in console mode. Table 1-1 lists the prompts and the mode of
operation each prompt represents.
