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, Type 4364 or Type 4365 server,” on page 59 to determine which componentsare 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 microprocessor is notworking correctly.1. Correct any errors that are indicated by the LEDs (see “System-board LEDs”on page 35).2. Make sure that the server supports the microprocessor.3. (Trained service technician only) Make sure that the microprocessor is seatedcorrectly.4. (Trained service technician only) Replace the microprocessor.Monitor 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, Type 4364 or Type 4365 server,” on page 59 to determine which componentsare 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 testing the monitor on adifferent 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.28 IBM System x3250 Types 4364 and 4365: Problem Determination and Service Guide
