To install a power supply:
3 Pull to open the handle on the new power supply, slide it all the way into the bay, and
then press the handle to seat the power supply and lock it in place.
4 Connect the power cord to the power supply.
If the Xserve is already running on a second power supply, the status light on the new
supply turns green to indicate normal operation as it starts sharing the load. If the
Xserve is not turned on, the supply status light blinks green when the power cord is
plugged in to an outlet with power.
Slide the power supply in and
press the handle to seat it.
