Connect the building wire LAN 1 wire (either PoE+ at or PoE af) to the black RJ45 connector using short patch cables. Alternatively, connect using the associated punch-down block. The connector and the punch-down block are located on the rear of the AP.
Additionally, you can connect the pass-through cable to the blue connector (top) on the back of the AP or its associated punch-down block.
When using the WALL05 bracket, you have the option to use the RJ45 loop cable or the RJ45 cable with a receptacle.
