Press this button to turn the server on and off. The states of the power-on LED are:

• Off: AC power is not present, or the power supply or the LED itself has failed.

• Flashing rapidly (4 times per second): the server is turned off and is not ready to be turned on. The power-control button is disabled. The power-control button becomes active approximately three minutes after the server is connected to AC power.

• Flashing slowly (once per second): the server is turned off and is ready to be turned on. You can press the power-control button to turn on the server.

• Lit: The server is turned on.

Note

If this LED is off, do not assume that electrical power is absent in the server. The LED might be burned out. To remove all electrical power from the server, you must disconnect the power cord from the electrical outlet.
