remove and reseat connectors on the system board. If the problem persists, replace the power

Troubleshooting Using the Front Panel Power Button
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.
If the server is off, and power is not connected to server power supplies, pressing the Power
button has no effect.
If the server is off, and power is connected to server power supplies, the front panel power LED
blinks at a 1 Hz rate. In this state, standby power is available to server circuits, but main power
is off. Pressing and holding the Power button accomplishes the following:
• 1 – 3 seconds: System power turns on.
If the server is on and the system is at the EFI, pressing and holding the Power button accomplishes
the following:
• 1 – 3 seconds: System power turns off immediately (hard power off).
• 5 seconds or longer: System power turns off immediately (hard power off).
If the server is on and the operating system is running, pressing and holding the Power button
accomplishes the following:
• 1 – 3 seconds: System power turns off (software controlled power off).
• 5 seconds or longer: System power turns off immediately (hard power off).
