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 41
◆
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.
