How to Connect to the RJ-45 Port
The connection between the AP’s RJ-45 port and a LAN switch requires an
unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. Use
Category 5, 5e or 6 cable for 1000BASE-T connections, Category 5 or better for
100BASE-TX connections, and Category 3 or better for 10BASE-T connections. The
length of the cable must be less than 100m (328 ft).
The RJ-45 port on the AP supports automatic MDI/MDI-X pinout configuration, so
you can use standard straight-through twisted-pair cables to connect to any other
network device (PCs, servers, switches, routers, or hubs).
Copper Cabling
Guidelines
To ensure proper operation when installing the AP into a network, make sure that
the current cables are suitable for 10BASE-T, 100BASE-TX or 1000BASE-T operation.
Check the following criteria against the current installation of your network:
◆
Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP) cables
with RJ-45 connectors; Category 3 or better for 10BASE-T, Category 5 or better
for 100BASE-TX, and Category 5, 5e or 6 for 1000BASE-T.
◆
Protection from radio frequency interference emissions
◆
Electrical surge suppression
◆
Separation of electrical wires (switch related or other) and electromagnetic
fields from data based network wiring
◆
Safe connections with no damaged cables, connectors or shields
