These checkpoints are referred to as ″amemory checkpoint″ in this MAP.Purpose of This MAPThis MAP is used to troubleshoot a problem during the memory test when the systemstops at a memory checkpoint and no 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 50.2. The service processor may have recorded one or more symptoms in its error log. Itis a good idea to examine that error log before proceeding (see Service ProcessorSystem Information Menu).3. The service processor may have been set by the user to monitor service operationsand to attempt recoveries. You might want to disable these actions while youdiagnose and service the system. If you disable them, make notes of their currentsettings so that you can restore them before you leave.
