i
Purpose of
Tests
If you cannot locate and/or resolve the system problem using
the troubleshooting tables in Chapter 13, you can run diagnostic
tests. Diagnostic tests can help to identify the source of a
problem and provide specific information to present to your
Digital service representative over the telephone.
Your Digital service representative may also request that you
run diagnostic tests.
What You
Should Have
Done Already
Before running diagnostic tests on your system to identify
a defective component or module, you should have already
completed these tasks:
• Shut down your operating system (if running) as described in
Chapter 7.
• Put your system into console mode.
• Tried to locate and resolve the problem with the information
in Chapter 13.
• Used the
show
commands to determine the system component
or device with an error. See Chapter 13.
If you have not completed these tasks, please refer to the
relevant sections earlier in this guide.
