The power-control button does not work, and the reset button does work (the server does not start).The power-control button will not function until approximately 20 to 40 seconds after the server has been connected to power. | - Make sure that the power-control button is working correctly:
- Disconnect the server power cords.
- Reconnect the power cords.
- (Trained service technician only) Reseat the operator information panel cables, and then repeat steps 1a and 1b.
- (Trained service technician only) If the server starts, reseat the operator information panel. If the problem remains, replace the operator information panel.
- If the server does not start, bypass the power-control button by using the force power-on jumper (see System-board switches and jumpers). If the server starts, reseat the operator information panel. If the problem remains, replace the operator information panel.
- Make sure that the reset button is working correctly:
- Disconnect the server power cords.
- Reconnect the power cords.
- (Trained service technician only) Reseat the light path diagnostics panel cable, and then repeat steps 1a and 1b.
- (Trained service technician only) If the server starts, replace the light path diagnostics panel.
- If the server does not start, go to step 3.
- Make sure that both power supplies installed in the server are of the same type. Mixing different power supplies in the server will cause a system error (the system-error LED on the front panel turns on and the PS and CNFG LEDs on the operator information panel are lit).
- Make sure that:
- The power cords are correctly connected to the server and to a working electrical outlet.
- The type of memory that is installed is correct.
- The DIMMs are fully seated.
- The LEDs on the power supply do not indicate a problem.
- The microprocessors are installed in the correct sequence.
- Reseat the following components:
- DIMMs
- Power supplies
- (Trained service technician only) Power switch connector
- Replace the components listed in step 5 one at a time, in the order shown, restarting the server each time.
- If you just installed an optional device, remove it, and restart the server. If the server now starts, you might have installed more devices than the power supply supports.

| The server does not turn off. | - Determine whether you are using an Advanced Configuration and Power Interface (ACPI) or a non-ACPI operating system. If you are using a non-ACPI operating system, complete the following steps:
- Press Ctrl+Alt+Delete.
- Turn off the server by pressing the power-control button and hold it down for 5 seconds.
- Restart the server.
- If the server fails POST and the power-control button does not work, disconnect the power cord for 20 seconds; then, reconnect the power cord and restart the server.
- If the problem remains or if you are using an ACPI-aware operating system, suspect the system board.
