10

At least 400 mm in front of the RU, and At least 20 mm at the rear of RU.
2.1.1 Wall Mount
Refer to the steps below to mount the RU to a wall. 1. Use a power tool to drill four holes,then insert the wall anchors into the holes. 2. Apply the four wall mounting screws into the wall anchors and fix the bracket.
3. At the bottom of the RU, place the four feet into the corresponding positions on the bracket and push down to slide it into the bracket. 11

4. Slide down the RU so the stopper on the bracket can fix it. 12

5. Apply security screw and finish assembly.

2.3 Powering on the RU
The RU can be powered via a PSE or a DC adaptor. If both are available, choose the DC adaptor over the PSE. Please make sure your PSE device can support 802.3bt, as the RU’s full loading power consumption will exceed 802.3at specifications.

The steps below describe ways of powering on the RU.

1. RU power source:
