When this LED is lit and not flashing, it indicates that the server is turned
on. When this LED is flashing, it indicates that the server is turned off and
still connected to an ac power source. When this LED is off, it indicates that
ac power is not present, or the power supply or the LED itself has failed. A
power LED is also on the rear of the server.
Note: If this LED is off, it does not mean that there is no electrical power in
the server. The LED might be burned out. To remove all electrical power
from the server, you must disconnect the power cords from the electrical
outlets.
