v Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. v See the parts listing in the Problem Determination and Service Guide to determine which components are customer replaceable units (CRU) and which components are field replaceable units (FRU). v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a trained service technician. Symptom Action The mouse or pointing device does not work. v Make sure that the mouse or pointing-device cable is securely connected to the server and that the keyboard and mouse cables are not reversed. v Make sure that the mouse device drivers are installed correctly. v Try using another mouse or pointing device. If the problem remains, call for service. Memory problems v Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. v See the parts listing in the Problem Determination and Service Guide to determine which components are customer replaceable units (CRU) and which components are field replaceable units (FRU). v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a trained service technician. Symptom Action The amount of system memory displayed is less than the amount of installed physical memory. Make sure that: v The DIMMs are seated correctly. v You have installed the correct type and capacity of memory. v You have installed the DIMMs in the correct slots, in the correct order. v If you changed the memory, you updated the memory configuration in the Configuration/Setup Utility program. v All banks of memory are enabled. The server might have automatically disabled a memory bank when it detected a problem, or a memory bank might have been manually disabled. Look in the POST error log for error message 289: v If the DIMM was disabled by a system-management interrupt (SMI), replace the DIMM. v If the DIMM was disabled by the user or by POST, run the Configuration/Setup Utility program and enable the DIMM. v If this error remains, replace the DIMM. If the problem remains, call for service. Chapter 6. Solving problems 55
