7-22 Upgrading your Server
Power Supply
The addition of a third hot-swap power supply makes your system so that it has redundant power
and can be operated continuously without interruption if either of the power supplies malfunction.
Installation
To install the optional hot-swap power supply, perform the following procedures:
1.
See the section Preparing for Upgrade described earlier in this chapter.
2.
At the rear of the cabinet locate the power supply bay, (with a blank cover over it), where
the optional power supply will be installed.
3.
Remove the blank cover by grasping its handle (1) with your right hand, press the latch
with your index finger, pull the handle down slightly (2), and slide the cover out of the bay
(3). Save the blank cover for future use.

Connect two power cords to the AC inlets.
Use the standard power cord coming with the server and the cord coming with the power
supply.

Turn on the system.
The AC power LEDs on the power supplies are lit. When the server is in redundant power
supply configuration, the ACR LED on the rear of the server lights up.
