Attention:
Index" on page 155. 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 101 unless otherwise indicated in the
tables.
v If you replace FRUs and the problem is corrected, go to "MAP 0410: Repair
Checkout" in the RS/6000 Eserver pSeries Diagnostic Information for Multiple Bus
Systems .
Note: Do not shut down the system if the FRU was replaced by hot swap.

Performing Slow Boot

On this system, the error code displayed in the operator panel may not indicate the root
cause of the problem. To fully analyze all of the available information, perform the
following steps before doing a hardware repair or replacement:
1. Record the 8-character error code (and location code if present) in the operator
panel.
2. Power down the system using the white botton. Refer to "Stopping the System" on
page 350.
3. Select slow boot mode (select disable fast boot) on the system power control menu
from the service processor main menu.
4. Do a slow-mode boot to the SMS menus. This boot can be specified using the
System Power Control Menu on the service processor main menu. Refer to "System
Power Control Menu" on page 296. (A fast-mode boot skips much of the built-in
diagnostic testing.) A slow-mode boot may yield a new 8-character error code on the
operator panel and new errors in the service processor error log. Power on the
system. Refer to "Starting the System" on page 350.
v If a new error code is reported, use it in subsequent steps to continue problem
v If the system hangs with the same error code, continue with the next step in the
v If no 8-character error code is displayed in the operator panel, use the original
5. Power off the system.
6. At this point, the service processor menus should be available to examine the
service processor error log.
