Error symptoms
You can use the error symptom table to find solutions to problems that have definite
symptoms.
If you cannot find the problem in the error symptom charts, go to "Starting the
diagnostic programs and viewing the test log" on page 22 to test the server.
If you have just added new software or a new option and your server is not
working, use the following procedures before using the error symptom charts:
v Remove the software or device that you just added.
v Run the diagnostic tests to determine whether the server is running correctly.
v Reinstall the new software or new device.
In the following table, if the entry in the FRU/action column is a suggested action,
perform that action; if it is the name of a component, reseat the component and
replace it if necessary. The most likely cause of the symptom is listed first.
