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 or from the
UPS.
