or longer
If the server is off, and power is not connected to server power supplies, pressing the Power button has no effect.

Server Power Button Function When Server is Off
System power turns on.
Press and hold the Power button for one to three
seconds
Server Does Not Power On
The server Power button on the front panel operates differently depending on how long you press
and hold the button, and on what the system is doing when the button is pressed. You must be
aware of the Power button functionality to properly troubleshoot the system.
NOTE:
If the server is off, and power is not connected to server power supplies, pressing the
Power button has no effect.
Power problems during installation are usually related to the installation process. If the server
does not power on, check the LED indicators on the power supply rear panels and take one of
the following actions:
•
If the
AC In
indicators are lit, power is available to the server.
•
If a fault indicator is lit, reseat the power supply. If the problem persists, remove and reseat
boards within the server. If the problem persists, replace the power supply or the power
supply interface board.
•
If the
AC Out
indicators are lit, power is available to the server circuits. If the console shows
that the server is powered on, but server LEDs indicate that power is off, remove and reseat
connectors on the LED status board. If the problem persists, replace the LED status board.
If the console shows that the server is not powered on, remove and reseat connectors on
the system board. If the problem persists, replace the power supply interface board, the iLO
2 MP board, or the system board.
