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 computer.
If you have just added new software or a new option and the computer 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 computer 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 Types 6223 and 6227,” on page 115 to determine which components are
replaceable by the customer (CRU), and which components must be replaced by a field service technician (FRU).
