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 is displayed 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 2-31
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).
3. The Service Processor may have been set by the user to monitor service
operations 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 Start From the Service Processor System Power
Control Menu, disable unattended start mode.
Reboot Policy From the System Power Control Menu, go to
the Reboot/Restart Policy Setup Menu and set:
1. Number of reboot attempts to 0 (zero)
2. Use OS-Defined restart policy to No
3. Enable supplemental restart policy to No.
Call Out From the Call-In/Call-Out Setup Menu, go to the
Serial Port Selection Menu and disable call-out
on both serial ports.
