Cables and Pinouts
C-2
The following figure illustrates how the pins on the RJ-45
connector are numbered. Be sure to hold the connectors in the
same orientation when attaching the wires to the pins.
10/100BASE-TX Pin Assignments
Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP)
cable for RJ-45 connections: 100-ohm Category 3 or better cable
for 10 Mbps connections, or 100-ohm Category 5 or better cable
for 100 Mbps connections. Also be sure
that the length of any
twisted-pair connection does not exceed 100 meters (328 feet).
The RJ-45 port on the access point is wired with MDI pinouts.
This means that you must use crossover cables for connections
to PCs or servers, and straight-through cable for connections to
switches or hubs. However, when connecting to devices that
support automatic MDI/MDI-X pinout configuration, you can use
either straight-through or crossover cable.
