Note: See Chapter 8, "Parts listing, Type 8482 and 8487," on page 99 to determine which components are replaceable by the customer (CRU), and which components must be replaced by a field service technician (FRU). Keyboard, mouse, or pointing-device problems Symptom FRU/action The mouse or pointing device does not work. 1. Verify that: v The mouse or pointing-device cable is securely connected, and that the keyboard and mouse cables are not reversed. v The mouse device drivers are installed correctly. 2. Mouse or pointing device. 3. System board. Note: See Chapter 8, "Parts listing, Type 8482 and 8487," on page 99 to determine which components are replaceable by the customer (CRU), and which components must be replaced by a field service technician (FRU). Memory problems Symptom FRU/action The amount of system memory displayed is less than the amount of physical memory installed. 1. Verify that: 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 on the DIMMs are enabled. The server might have automatically disabled a DIMM bank when it detected a problem or a DIMM bank could 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 server. 3. DIMM. 4. System board.
