AC POWER Lamp
There is an AC POWER lamp for the power supply unit on the rear. The lamp turns green and
flashes when the power supply unit receives AC power from the power cord, which is connected to
the AC inlet.
The lamp turns green when the server power switch is turned on. If the lamp does not go on when
the server power switch is turned on or if it turns or blinks amber, the power supply unit is probably
faulty. In this case, contact your sales representative to replace the power supply unit.
NOTE:
If one power supply unit fails while an optional power supply
is mounted, the system can continue operation with the other power
supply unit. (Redundant function) The failing power supply unit can
be replaced in hot swap mode (with the power on) without the system
being stopped.
