Diagnostic Programs, Messages, And Error Codes; Running The Diagnostic Programs - IBM System x3250 Problem Determination And 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 39.

Running the diagnostic programs

To run the diagnostic programs, complete the following steps:
10. Select Save & Exit Setup and follow the prompts. The diagnostic programs
11. From the diagnostic programs screen, select the test that you want to run, and
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 39.
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 28 for information about diagnosing
microprocessor problems.
The baseboard management controller heatbeat LED flashes to indicate that the
mini-BMC is functioning correctly.
The standby power LED is lit whenever the server is connected to ac power.
1. If the server is running, turn off the server and all attached devices.
