Troubleshooting tables
Use the troubleshooting tables to find solutions to problems that have identifiable
symptoms. See the Problem Determination and Service Guide on the IBM System x
Documentation CD for more detailed troubleshooting information. If you cannot find
the problem in these tables, run the diagnostic programs (see “Running the
diagnostic programs” in the Problem Determination and Service Guide).
If you have just added new software or a new optional device and the server is not
working, complete the following steps before using the troubleshooting tables:
1. Check the light path diagnostics LEDs (see “Light path diagnostics” on page
68).
2. Remove the software or device that you just added.
3. Run the diagnostic tests to determine whether the server is running correctly.
4. Reinstall the new software or new device.
