Diagnostic programs and messages
The diagnostic programs are the primary method of testing the major components of the server. As you
run the diagnostic programs, text messages are displayed on the screen and are saved in the test log. A
diagnostic text message indicates that a problem has been detected and provides the action you should
take as a result of the text message.
Utilities are available to reset and update the diagnostics code on the integrated USB flash device, if the
diagnostic partition becomes damaged and does not start the diagnostic programs. For more information
and to download the utilities, go to http://www.lenovo.com/support.
