MAP 1240: Memory Problem Resolution

Note:
The firmware checkpoint that sent you here could be one of the following:
E122, E213, E214, E218, E220 or E3xx
These checkpoints are referred to as "a memory checkpoint" in this MAP.
Purpose of this MAP
This MAP is used to trouble shoot a problem during the memory test when the
system stops at a memory checkpoint and no error code displays on the operator
panel.
Notes:
1. If the symptom changes while 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 2-37.
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). Check the memory configuration in the
service processor menus. If a memory module has been deconfigured by the
system, swap the memory module positions on the memory card. The system
interprets this as an indication that the memory modules have been replaced. If
this does not work, perform the following steps:
Manually configure the memory module.
Reseat the memory card or module.
Re-ipl the system.
3. The Service Processor may have been set by the user to monitor server oper-
ations and to attempt recoveries. You may wish to disable these actions while
you diagnose and service the system. If you disable them, you should make
notes of their current settings for restoration before you leave. Following are the
settings of your interest.
Surveillance From the service Processor Setup Menu, go to the Surveillance Setup Menu
and disable surveillance.
Unattended From the Service Processor System Power Control Menu disable unattended
Start start mode.
