Troubleshooting tables
Use the troubleshooting tables to find solutions to problems that have identifiable
symptoms. See the Hardware Maintenance Manual on the ThinkServer
Documentation DVD 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 Hardware Maintenance Manual).
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 on the operator information panel (see
“Light path diagnostics” on page 77).
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.
