Purpose of This MAP
This MAP is used to troubleshoot a problem when the system stops with a memory checkpoint or memory
error code on the operator panel display or console.
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 1548: Processor Subsystem Problem Isolation” on
page 139.
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 might want to disable these actions while you diagnose and service the system. If you
disable them, make note of their current settings so that you can restore them before you leave. The
following settings may be of interest to you.
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.
General Memory Information
Be sure to unplug the power cables before removing or installing the processor cards or memory DIMMs
to avoid damage to them.
It is acceptable for the memory DIMMs to partially populate each processor card in a multi-processor card
system. For example, 4 memory DIMMs can be placed onto processor card 1, and another 4 memory
DIMMs can be placed onto processor card 2. The system uses both sets of memory DIMMs
indiscriminately.
