Checkout procedure
The checkout procedure is the sequence of tasks that you should follow to
diagnose a problem in the server.
About the checkout procedure
Before you perform the checkout procedure for diagnosing hardware problems,
review the following information:
v Read the safety information that begins on page vii.
v The diagnostic programs provide the primary methods of testing the major
components of the server, such as the system board, Ethernet controller,
keyboard, mouse (pointing device), serial ports, and hard disk drives. You can
also use them to test some external devices. If you are not sure whether a
problem is caused by the hardware or by the software, you can use the
diagnostic programs to confirm that the hardware is working correctly.
v When you run the diagnostic programs, 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 multiple error codes or light path diagnostics LEDs indicate a
microprocessor error, the error might be in the microprocessor or in the
