v Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.
v
See Chapter 3, “Parts listing, Type 7981 and 1884,” on page 53 to determine which components are
customer replaceable units (CRU) and which components are field replaceable units (FRU).
v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.
Error code Description Action

Checkout procedure
The checkout procedure is the sequence of tasks that you should follow to
diagnose a problem in the blade server.
About the checkout procedure
Before performing 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 blade server. 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 there are multiple error codes or light path diagnostics LEDs that
indicate a microprocessor error, the error might be in a microprocessor or in a
microprocessor socket. See “Microprocessor problems” on page 30 for
information about diagnosing microprocessor problems.
v
If the blade server is halted and a POST error code is displayed, see “Error logs”
on page 16. If the blade server is halted and no error message is displayed, see
“Troubleshooting tables” on page 25 and “Solving undetermined problems” on
page 49.
v
For intermittent problems, check the error log; see “Error logs” on page 16 and
“Diagnostic programs, messages, and error codes” on page 41.
v If no LEDs are lit on the blade server front panel, verify the blade server status
and errors in the management-module Web interface; also see “Solving
undetermined problems” on page 49.
v
If device errors occur, see “Troubleshooting tables” on page 25.
