These programs are the primary method of testing the majorcomponents of the server.Diagnostic error messages indicate that a problem exists; they are not intended tobe used to identify a failing part. Troubleshooting and servicing of complexproblems that are indicated by error messages should be performed by trainedservice personnel.Sometimes the first error to occur causes additional errors. In this case, the serverdisplays more than one error message. Always follow the suggested actioninstructions for the first error message that appears.Starting the diagnostic programsTo start the diagnostic programs:1. Turn on the server and watch the screen.2. When the message F2 for Diagnostics appears, press F2.If a power-on password is set, the server prompts you for it. Type the power-onpassword, and press enter.3. When the Diagnostic Programs screen appears, select either Extended orBasic from the top of the screen.4.

If the server stops during testing and you cannot continue, restart the serverand try running the diagnostic programs again. If the problem remains, flashthe server with the latest diagnostics code and BIOS, and then run the testagain. If the problem remains, see “Undetermined problems” on page 143.b.
