Table 5-3 Server Power Button Functions When Server is Off
ReactionAction
System power turns on.1-3 seconds
Server Does Not Power On
The server Power button on the front panel operates differently depending on how long the
button is held in, 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, check the LED indicators on the power supply rear panels and follow these
steps.
• If the DC In indicators are lit, it is assumed that 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 DC Out indicators are lit, it is assumed that 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 (server is off),
remove and reseat connectors on the system board. If the problem persists, replace the power
supply interface board, the MP card, or the system board.
