Troubleshooting tables
Use the troubleshooting tables to find solutions to problems that have identifiable
symptoms.
If you cannot find a problem in these tables, see “Running the diagnostic programs”
on page 190 for information about testing the server.
If you have just added new software or a new optional device and the server is not
working, complete the following steps before you use the troubleshooting tables:
1. Check the system-error LED on the operator information panel; if it is lit, check
the light path diagnostics LEDs (see “Light path diagnostics” on page 187).
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.
