System Power Light: When this green light is on,
system power is present in the server. When this
light flashes, the server is in standby mode (the
system power supply is turned off and AC current is
present). When this light is off, either a power
supply, AC power, or a light has failed.
Attention
If this light is off, it does not mean there is no
electrical current present in the server. The
light might be burned out. To remove all
electrical current from the server, you must
unplug the server power cords from the
electrical outlets.
