򍦠 System power light: When this green light is on, 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,
the power subsystem, the ac power, or a light has failed.
Attention: If the system power 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 uninterruptible power device.
