Access Point Port and
Network Cables
Crossover Twisted-Pair Cable for
10 Mbps or 100 Mbps Network Connection
Because the 10/100 port on the access point uses an MDI pin configuration,
you must use “crossover” cable for network connections to PCs, servers or
other end nodes that only have MDI ports. However, if the device to which you
are connecting supports auto-MDIX operation, you can use either “straight-
through” or “crossover” cable.
Cable Diagram
Note Pins 1 and 2 on connector “A” must be wired as a twisted pair to pins 3 and 6
on connector “B”.
Pins 3 and 6 on connector “A” must be wired as a twisted pair to pins 1 and 2
on connector “B”.
Pins 4, 5, 7, and 8 are not used for transmitting or receiving data, although they
must be wired straight-through in the cable to support Power over Ethernet.
