Microprocessor error symptoms Note: See "System replaceable units" on page 144 to determine which components should be replaced by a field service technician. 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 properly. 2. (Trained service technician only) Remove microprocessor 2 and restart the server. v If no beep code occurs, microprocessor 2 might have failed; replace the microprocessor. v If the beep code remains, remove microprocessor 1 and install microprocessor 2 in the connector for microprocessor 1; then, restart the server. If no beep code occurs, microprocessor 1 might have failed; replace the microprocessor. 3. Startup microprocessor. Monitor error symptoms Note: See "System replaceable units" on page 144 to determine which components should be replaced by a field service technician. Symptom FRU/action Monitor problems (general). Some IBM monitors have their own self-tests. If you suspect a problem with the monitor, refer to the information that comes with the monitor for adjusting and testing instructions. 1. Monitor. 2. Run video diagnostics. If diagnostics pass, the problem may be a video driver. 3. Display adapter / system board. 126 xSeries 236 Type 8841: Hardware Maintenance Manual and Troubleshooting Guide
