Server Does Not Power On

The server Power button on the front panel operates differently depending on how long the
button is held, and on what the server is doing when the button is pressed. You must be aware
of its uses to properly troubleshoot the server.
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 follow these
steps.
• 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. Reseat the power supply. If the problem persists, remove and reseat the board
within the server. If the problem persists, replace the power supply or the power supply
interface board.
• 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 (server is off), remove and reseat
connectors on the system board. If the problem persists, replace the power supply interface
board, or the system board.
