Chapter 5. Error Code to FRU Index
Attention:
Index" on page 165. In this section, you may be asked to perform additional isolation
procedures before looking up the actions for a 4-character checkpoint or 8-character
error code.
The Error Code to FRU Index lists fault symptoms and possible causes. The most likely
cause is listed first. Use this index to help you decide which FRUs to replace when
servicing the system.
v If you replace FRUs or perform an action and the problem is still not corrected, go to
"MAP 1540: Minimum Configuration" on page 113 unless otherwise indicated in the
tables.
v If you replace FRUs and the problem is corrected, go to "MAP 410: Repair
Checkout" in the RS/6000 and Eserver pSeries Diagnostics Information for Multiple
Bus Systems.
Note: Do not shut down the system if the FRU was replaced by hot swap.
Four-Character Checkpoints
Four-character progress codes and checkpoints in the form 8xxx, 9xxx, Axxx, Bxxx, and
Exxx are listed in "Firmware Checkpoints" on page 147. If you have a four-character
code that begins with any character other than 8, 9, A, B, or E, refer to the RS/6000
and Eserver pSeries Diagnostics Information for Multiple Bus Systems.
Replacing the Primary Drawer Operator Panel
Licensed programs frequently rely on system information that is stored in the VPD
module on the primary drawer's operator panel. If the MAPs indicate that the operator
panel should be replaced, the pluggable VPD module must be swapped. If the old
module is defective, or cannot be recovered, contact service support.
Replacing the Network Adapter
If a network adapter is replaced, the network administrator must be notified so that the
client IP addresses used by the server can be updated. In addition, the operating
system configuration of the network controller may need to be changed in order to
enable system startup. Also check to ensure that any client or server that accesses this
system is updated.
Analyzing SPCN Errors on Secondary Drawers
The drawer number of a secondary I/O drawer (which displays in the operator panel in
the form U0.n, where n is the drawer number) does not change unless a repair action or
a configuration change has occurred. However, after a secondary I/O drawer has been
removed, added, or had its backplane replaced, there is a window of time during the
