Microprocessor problemsv Follow the suggested actions in the order in which they are listed in the Action column until the problemis solved.v See Chapter 3, “Parts listing, System x3200 Types 4362 and 4363,” on page 67 to determine whichcomponents 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 atrained service technician.Symptom ActionThe server emits a continuousbeep during POST, indicatingthat the startup (boot)microprocessor is not workingcorrectly.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, restartingthe server each time:a. (Trained service technician only) Microprocessorb. (Trained service technician only) System boardMonitor or video problemsSome IBM monitors have their own self-tests. If you suspect a problem with yourmonitor, see the documentation that comes with the monitor for instructions fortesting and adjusting the monitor.v Follow the suggested actions in the order in which they are listed in the Action column until the problemis solved.v See Chapter 3, “Parts listing, System x3200 Types 4362 and 4363,” on page 67 to determine whichcomponents 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 atrained service technician.Symptom ActionTesting 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 beingtested 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. (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 “Powerproblems” on page 38.v The monitor cables are connected correctly.v The monitor is turned on and the brightness and contrast controls areadjusted correctly.v A single beep sounds when the server is turned on, indicating the successfulcompletion 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 “Recoveringfrom a BIOS update failure” on page 53.4. See “Solving undetermined problems” on page 64.Chapter 2. Diagnostics 35
