1000BASE-T Cable Requirements
All Category 5 UTP cables that are used for 100BASE-TX connections should also
work for 1000BASE-T, providing that all four wire pairs are connected. However, it is
recommended that for all critical connections, or any new cable installations,
Category 5e (enhanced Category 5) or Category 6 cable should be used. The
Category 5e and 6 specifications include test parameters that are only
recommendations for Category 5. Therefore, the first step in preparing existing
Category 5 cabling for running 1000BASE-T is a simple test of the cable installation
to be sure that it complies with the IEEE 802.3-2008 standards.
Follow these steps to connect Ethernet copper cable to the AP's RJ-45 twisted-pair
copper port:
Note:
Connecting the Ethernet cable to the AP powers on the unit.

Disassemble the waterproof port cover into its five parts:; the outer screw-on
cover, the screw-on cable clamp, the inner plastic RJ-45 plug cover, the inner
rubber cable seal, and the rubber port seal.
