These checkpoints and error codes are referred to as a memory code in this MAP.
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 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 77.
2. The service processor might have recorded one or more symptoms in its error log. It is a good idea to
examine that error log before proceeding. (See "Accessing system error logs" on page 36.)
3. The service processor might 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 might be of interest to you.
Surveillance
Unattended start
Reboot policy
Call out
General memory information
Be sure to unplug the power cables before removing or installing the processor cards or DIMMs to avoid
damage to them.
It is acceptable for the DIMMs to partially populate each processor card in a multiprocessor card system.
For example, four DIMMs can be placed onto processor card 1, and another four DIMMs can be placed
onto processor card 2. The system uses both sets of DIMMs indiscriminately.
See "DIMMs" on page 346 for more information on valid memory configurations.
