The power-control button does not work, and the
reset button does not work (the server does not start). Note: 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. 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 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.
- 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).
- 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:
- Operator information panel connector
- Power supplies
- 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.

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