Note: See Chapter 7, "Parts listing, Types 8861, 8862," on page 139 to determine which components are replaceable by the customer and which components must be replaced by an IBM field service technician. Memory problems Symptom FRU/action The amount of system memory displayed is less than the amount of physical memory installed. 1. Verify that: v No error LEDs are lit on the operator information panel or in the memory cassette. v Memory mirroring does not account for the mismatch. v The memory modules are seated properly. v You have installed the correct type of memory. v If you changed the memory, you updated the memory configuration with 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. 2. Check 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: a. Start the Configuration/Setup Utility program. b. Enable the DIMM. c. Save the configuration and restart the computer. 3. DIMM. 4. Memory cassette[ Note: See Chapter 7, "Parts listing, Types 8861, 8862," on page 139 to determine which components are replaceable by the customer and which components must be replaced by an IBM field service technician. Microprocessor problems Symptom FRU/action The server emits a continuous tone during POST. (The startup (boot) microprocessor is not working properly.) 1. Verify that the startup microprocessor is seated correctly. 2. Startup microprocessor. 3. Microprocessor VRM 3 or 4. 4. Microprocessor tray assembly. Note: See Chapter 7, "Parts listing, Types 8861, 8862," on page 139 to determine which components are replaceable by the customer and which components must be replaced by an IBM field service technician. Monitor problems Symptom FRU/action Testing the monitor. See the information that comes with the monitor for adjusting and testing instructions. (Some IBM monitors have their own self-tests.) 1. Monitor. 2. Run diagnostic programs. If diagnostic programs pass, the problem may be a video driver. 3. Remote Supervisor Adapter II. 4. I/O board. Chapter 6. Symptom-to-FRU index 125
