Troubleshooting charts
You can use the troubleshooting charts in this section to find solutions to problems
that have definite symptoms.
Attention: If diagnostic error messages appear that are not listed in the following
tables, make sure that your server has the latest levels of BIOS, ServeRAID, and
diagnostics microcode installed.
See “Starting the diagnostic programs” on page 88 to test the server. If you have run
the diagnostic test programs or if running the tests does not reveal the problem, call
for service.
Look for the symptom in the left column of the chart. Instructions and probable
solutions to the problem are in the right column. If you have just added new software
or a new option and your server is not working, do the following before using the
troubleshooting charts:
• Remove the software or device that you just added.
• Run the diagnostic tests to determine if your server is running correctly.
• Reinstall the new software or new device.
