Troubleshooting tables
Use the troubleshooting tables to find solutions to problems that have identifiable
symptoms. See the Hardware Maintenance Manual for more detailed troubleshooting
information. If you cannot find a problem in these tables, run the diagnostic

Manual).
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-board LEDs or the LEDs on the front panel (see
“System-board LEDs” on page 75).
