How to Connect to the RJ-45 Port

The connection between the AP’s RJ-45 port and the PoE power injector requires

outdoor-rated Category 5E or better Ethernet cable with RJ-45 plugs on each end.

The length of the Ethernet cable should be less than 100 meters (328 ft).

Copper Cabling

Guidelines

Before connecting the Ethernet copper cable, first plan a cable route from the AP

outdoors to the PoE power injector indoors. Consider these guidelines:

◆ Make sure the cable distance does not exceed 100 meters (328 ft).

◆ Determine a building entry point for the cable.

◆ Determine if conduits, bracing, or other structures are required for safety or

protection of the cable.

◆ Be sure to ground the outdoor-rated Ethernet cable immediately before it

enters the building. See “Grounding the Ethernet Cable” on page 38.

◆ For additional lightning protection, it is recommended to use a lightning

arrestor immediately before the Ethernet cable enters the building.

10/100BASE-TX Pin

Assignments

Most 100BASE-TX RJ-45 ports support automatic MDI/MDI-X operation, so you can

use straight-through or crossover cables for all network connections to PCs,

switches, or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one end of the

cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of the

cable.
