RJ45 loop back connector will be required, which the following covers.
To make the RJ45 loop connector:
Cut the sheath on Orange-White wire (2) and Green wire (6) and twist them together.
Cut the sheath on Green-White wire (3) and Orange wire (1) and twist them together.
Using the RJ45 loop back connector (wires 1 and 3 and wires 2 and 6):
1.- Connect RJ45 loop back connector to port FE2.
2.- Power on the AP.
3.- Wait for 2 minutes (probably not necessary to wait 2 minutes, but seems to produce better results when waiting 2 minutes)
4.- Disconnect the RJ45 loop back connector, and power off the AP.
5.- Power on the AP again, without RJ45 loop back connector physically connected. In about 2 minutes, the APs registered MAC address should be visible on the switch.
