Power problemsv Follow the suggested actions in the order in which they are listed in the Action column until the problemis solved.v See the parts listing in the Problem Determination and Service Guide to determine which components arecustomer 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 power-control button doesnot work (the server does notstart).Note: The power-control buttonwill not function until 20seconds after the server hasbeen connected to ac power.1. Make sure that the front-panel assembly power-control button is workingcorrectly:a. Disconnect the server power cords.b. Reconnect the power cords.c. Press the power-control button.d. If the server does not start, bypass the front-panel assembly power-controlbutton by using the force power-on jumper (see the Problem Determinationand Service Guide on the IBM System x Documentation CD). If the serverstarts, reseat the front-panel assembly cable and repeat steps 1a through1c. If the problem remains, replace the front-panel assembly.2. Make sure that:v The power cords are correctly connected to the server and to a workingelectrical outlet.v The server contains the correct type of DIMMs.v The DIMMs are correctly seated.v The LEDs on the power supply do not indicate a problem.v The microprocessor is correctly installed.3. Reseat the following components:a. DIMMsb. Power supply cables to all internal componentsc. Power supplies (hot-swap models)4. Replace the following components one at a time, in the order shown, restartingthe server each time:a. DIMMsb. Power supplies (hot-swap models)c. (Trained service technician only) Power supply (non-hot swap models)5. If you just installed an optional device, remove it, and restart the server. If theserver now starts, you might have installed more devices than the power supplysupports.6. See “Solving undetermined problems” in the Problem Determination andService Guide on the IBM System x Documentation CD.The server does not turn off. 1. Determine whether you are using an Advanced Configuration and PowerManagement (ACPI) or a non-ACPI operating system. If you are using anon-ACPI operating system, complete the following steps:a. Press Ctrl+Alt+Delete.b. Turn off the server by holding the power-control button for 5 seconds.c. Restart the server.d. If the server fails POST and the power-control button does not work,disconnect the ac power cord for 20 seconds; then, reconnect the ac powercord and restart the server.2. (Trained service technician only) If the problem remains or if you are using anACPI-aware operating system, suspect the system board.Chapter 5. Solving problems 69
