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 1.a and 1.b.
- (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, jumpers, and buttons). 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 technician only) Reseat the operator information panel cable, and then repeat steps 2.a and 2.b.
- (Trained technician only) If the server starts, 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 DIMMs are fully seated.
- The LEDs on the power supply do not indicate a problem.
- The microprocessors are installed in the correct sequence.
