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. (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.

NOTES:
„
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.
„
In configuration of two power units, AC power may be supplied only to a single power unit
through the power cord connected to the power unit. If so, the power lamp on the other power
unit (to which a power cord is not connected) blinks amber. When a power cord is connected to
the power unit to supply AC power, the lamp changes to blink green. If the lamp still blinks
amber, contact your service representative to ask maintenance.
