2-18 General Description
AC POWER LED (Redundant Power Supply Model)
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. (Flashing amber indicates no AC power is received in any one of two power supplies
in the redundant configuration.)
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 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.
