Powering the Devices

AC Power

There is a 12-outlet power bar mounted on the right-rear leg of the network equipment shelf. That power bar is plugged into a UPS. The UPS is plugged into a 10-outlet power bar mounted under the back edge of the desk, and it, in turn, is plugged into the AC wall outlet under the desk.
