Server does not power on
Complete the following steps until the problem is resolved:
Note:
The power-control button will not function until approximately 5 to 10 seconds after the server has
been connected to power.
1. Make sure that the power-control button is working correctly:
a. Disconnect the server power cords.
b. Reconnect the power cords.
c. (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.
If the server starts, reseat the operator information panel. If the problem remains, replace the
operator information panel.
2. Make sure that the reset button is working correctly:
a. Disconnect the server power cords.
b. Reconnect the power cords.
c. (Trained technician only) Reseat the operator information panel cable, and then repeat steps 2a and
2b.
• (Trained technician only) If the server starts, replace the operator information panel.
• If the server does not start, go to step 3.
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).
4. 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 processors are installed in the correct sequence.
