Undocumented problems

If you have completed the diagnostic procedure and the problem remains, the
problem might not have been previously identified by IBM. After you have
verified that all code is at the latest level, all hardware and software configurations
are valid, and no light path diagnostics LEDs or log entries indicate a hardware
component failure, contact IBM or an approved warranty service provider for
assistance.
To open an online service request, go to http://www.ibm.com/support/entry/
portal/Open_service_request. Be prepared to provide information about any error
codes and collected data and the problem determination procedures that you have
used.

Service bulletins

This information provides the location where can find Service bulletins to help you
solve problems.
IBM continually updates the support website with the latest tips and techniques
that you can use to solve problems that you might have with the IBM System
x3750 M4 server.
To find service bulletins that are available for the IBM System x3750 M4 server, go
to http://www.ibm.com/supportportal/ and search for 8722 or 8733, and retain.

Checkout procedure

This information provides tasks that you should follow to diagnose problems.
The checkout procedure is the sequence of tasks that you should follow to
diagnose a problem in the server.

About the checkout procedure

This information covers what you need to know before you use the checkout
procedure to determine server hardware problems.
Before you perform the checkout procedure for diagnosing hardware problems,
review the following information:
v Read the safety information that begins on page "Safety" on page vii.
v IBM Dynamic System Analysis (DSA) provides the primary methods of testing
v When you run DSA, a single problem might cause more than one error message.

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.
When this happens, correct the cause of the first error message. The other error
messages usually will not occur the next time you run DSA.
Exception: If multiple error codes or light path diagnostics LEDs indicate a
microprocessor error, the error might be in the microprocessor or in the
microprocessor socket. See "Microprocessor problems" on page 199 for
information about diagnosing microprocessor problems.
