If the symptom changes while you are using this MAP, check for loose cards, cables, and obviousproblems. If you do not find a problem, go to “MAP 1548: Processor Subsystem Problem Isolation” onpage 113.2. The service processor may have recorded one or more symptoms in its error log. It is a good idea toexamine 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 attemptrecoveries. You might want to disable these actions while you diagnose and service the system. If youdisable them, make note of their current settings so that you can restore them before you leave. Thefollowing settings may be of interest to you.Surveillance From the Service Processor Setup Menu, go to theSurveillance 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 theReboot/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 SerialPort Selection Menu and disable call-out on both serialports.General Memory InformationBe sure to unplug the power cables before removing or installing memory DIMMs to avoid damage tothem.Memory DIMMs must be installed in matched (size and speed) quads. Refer to “Memory DIMMs” on page355 for labeling of the system backplane and instructions on memory DIMM removal and installation. Donot, however, replace the covers as directed while troubleshooting this problem. Memory DIMM quads canonly be installed in one of the following two memory DIMM slot combinations:v 1, 3, 6, and 8Chapter 3. Maintenance Analysis Procedures (MAPs) 69
