Microprocessor 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 Chapter 3, "Parts listing, System x3200 M2 Types 4367 and 4368," on page 33 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 server emits a continuous beep during POST, indicating that the startup (boot) microprocessor is not working correctly. 1. Make sure that the microprocessor is supported on this server. 2. (Trained service technician only) Reseat the microprocessor. 3. Replace the following components one at a time, in the order shown, restarting the server each time: a. (Trained service technician only) Microprocessor b. (Trained service technician only) System board Monitor or video problems Some IBM monitors have their own self-tests. If you suspect a problem with your monitor, see the documentation that comes with the monitor for instructions for testing and adjusting the monitor. v Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. v See Chapter 3, "Parts listing, System x3200 M2 Types 4367 and 4368," on page 33 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 Testing the monitor 1. Make sure that the monitor cables are firmly connected. 2. Try using a different monitor on the server, or try using the monitor that is being tested on a different server. 3. Run the diagnostic programs. If the monitor passes the diagnostic programs, the problem might be a video device driver. 4. Reseat the Remote Supervisor Adapter II SlimLine (if one is installed). 5. Replace the Remote Supervisor Adapter II SlimLine. 6. (Trained service technician only) Replace the system board. The screen is blank. 1. Make sure that: v The server is turned on. If there is no power to the server, see "Power problems" on page 148. v The monitor cables are connected correctly. v The monitor is turned on and the brightness and contrast controls are adjusted correctly. v A single beep sounds when the server is turned on, indicating the successful completion of POST. 2. Make sure that the correct server is controlling the monitor, if applicable. 3. Make sure that damaged BIOS code is not affecting the video; see "Updating (flash-update) the BIOS code on the server" on page 216. 4. See "Solving undetermined problems" on page 229. Chapter 5.
