Server does not power on

The server power button on the front panel operates differently depending on how long the button
is pressed, and on what the system is doing when the button is pressed. You must be aware of its
uses 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, view the LED indicators on the power supply rear panels and perform the following:
If the ac power LED on the power supply on the rear panel of the server is lit, power is available
to the server.
If the ac power LED is not lit, the server is either in standby power mode, or there is a problem.
Re-seat the power supply. If the problem persists, remove and re-seat the board within the
server. If the problem persists, replace the power supply or the power supply interface board.
