MAP 1240: Memory Problem Resolution

Note: The firmware checkpoint that sent you here could be one of the following: E122,
Purpose of This MAP
This MAP is used to troubleshoot a problem during the memory test when the system
stops at a memory checkpoint and/or a error code is displayed on the operator panel.
Notes:
1. If the symptom changes while you are using this MAP, check for loose cards,
cables, and obvious problems. If you do not find a problem, go to "MAP 1540:
Minimum Configuration" on page 63.
2. The service processor may have recorded one or more symptoms in its error log. It
is a good idea to examine that error log before proceeding (see Service Processor
System Information Menu). If you find an obvious problem, fix the problem; then go
to "MAP 0410: Repair Checkout" in the RS/6000 Eserver pSeries Diagnostic
Information for Multiple Bus Systems .
3. The service processor may have been set by the user to monitor service operations
and to attempt recoveries. You might want to disable these actions while you
diagnose and service the system. If you disable them, make notes of their current
settings so that you can restore them before you leave. The following settings may
be of interest to you.
