Diagnostic Programs, Messages, And Error Codes; Running The Diagnostic Programs - IBM x3655 - System - 7985 Service Manual

Diagnostic programs, messages, and error codes

The diagnostic programs are the primary method of testing the major components
of the server. As you run the diagnostic programs, text messages and error codes
are displayed on the screen and are saved in the test log. A diagnostic text
message or error code indicates that a problem has been detected; to determine
what action you should take as a result of a message or error code, see the table in
"Diagnostic error codes" on page 145.

Running the diagnostic programs

To run the diagnostic programs, complete the following steps:
1. If the server is running, turn off the server and all attached devices.
2. Turn on all attached devices; then, turn on the server.
3. When the prompt F2 for Diagnostics appears, press F2. If you have set both a
4. From the top of the screen, select either Extended or Basic.

For help with the diagnostic programs, press F1. You also can press F1 from within
a help screen to obtain online documentation from which you can select different
categories. To exit from the help information, press Esc.
To determine what action you should take as a result of a diagnostic text message
or error code, see the table in "Diagnostic error codes" on page 145.
If the diagnostic programs do not detect any hardware errors but the problem
remains during normal server operations, a software error might be the cause. If
you suspect a software problem, see the information that comes with your software.
A single problem might cause more than one error message. When this happens,
correct the cause of the first error message. The other error messages usually will
not occur the next time you run the diagnostic programs.
Exception: If there are multiple error codes or diagnostics LEDs that indicate a
microprocessor error, the error might be in a microprocessor or in a microprocessor
socket. See "Microprocessor problems" on page 131 for information about
diagnosing microprocessor problems.
If the server stops during testing and you cannot continue, restart the server and try
to run the diagnostic programs again. If the problem remains, replace the
component that was being tested when the server stopped.
The keyboard and mouse (pointing device) tests assume that a keyboard and
mouse are attached to the server. If no mouse or a USB mouse is attached to the
server, you cannot use the Next Cat and Prev Cat buttons to select categories. All
other mouse-selectable functions are available through function keys. You can use
