General Description 2-15

AC POWER LED

There is an AC POWER LED for the power supply unit on the rear. The LED turns green and flashes when the power supply unit receives AC power from the power cord, which is connected to the AC inlet.

The LED turns green when the server power switch is turned on. If the LED 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 service 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.
