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, run the diagnostic
programs to test the server.
If you have just added new software or a new option and the server is not working,
complete the following steps before using the error symptom charts:
1. Remove the software or device that you just added.
2. Run the diagnostic tests to determine whether the server is running correctly.
3. 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.
Note: See Chapter 7, "Parts listing Type 8488 and 8648," on page 129 to determine which components are
replaceable by the customer (CRU), and which components must be replaced by a field service technician (FRU).
