If you cannot find the problem in the error symptom charts, go to "Starting the diagnostic programs" on page 22 to test the server. If you have just added new software or a new option and the server is not working, do the following before using the error symptom charts: v Remove the software or device that you just added. v Run the diagnostic tests to determine if 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. Chapter 8. Symptom-to-FRU index 77
