The power-control button does not work, and the reset button does not work (the server does not start).The power-control button will not function until approximately 5 to 10 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 technician only) Reseat the operator information panel cable, and then repeat steps 1a and 1b.
- (Trained 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 power cords are correctly connected to the server and to a working electrical outlet.
- The type of memory that is installed is correct.
- The DIMM is 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
- (Trained technician only) Power switch connector
- (Trained technician only) Power backplane
- Replace the following components one at a time, in the order shown, restarting the server each time:
- DIMMs
- (Trained technician only) Power switch connector
- (Trained technician only) Power backplane
- (Trained technician only) System board
- 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 for 5 seconds.
- Restart the server.
- If the server fails POST and the power-control button does not work, disconnect the power cord for 5 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.

The server unexpectedly shuts down, and the LEDs on the operator information panel are not lit. | See Solving undetermined problems. |
