Symptom-to-FRU index
This index supports IntelliStation Z Pro Type 6221 servers.
Notes:
1. Check the configuration before you replace a FRU. Configuration problems can
cause false errors and symptoms.
2. The default configuration can be loaded by starting the system and then
pressing the reset button four times, waiting 15 seconds between each press.
Once the configuration has reset to the default, it must be saved in Setup to be
stored in CMOS.
3. For IBM devices not supported by index, refer to the manual for that device.
4. Always start with “General checkout” on page 1.
The Symptom-to-FRU lists symptoms, errors, and the possible causes. The most
likely cause is listed first. Use this Symptom-to-FRU index to help you decide which
FRUs to have available when servicing the computer. The POST BIOS displays
POST error codes and messages on the screen.
The initial column or columns of the tables in this index lists error codes or
messages, and the final column lists one or more suggested actions or FRUs to
replace. Take the action (or replace the FRU) suggested first in the list of the
entries in the final column, and then restart the computer to see if the problem has
been corrected.
Note: Try reseating a suspected component or reconnecting a cable before
replacing the component.
