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 140.
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 F1 for Configuration/Setup is displayed, press F1.
