Straight-Through Twisted-Pair Cable for
10 Mbps or 100 Mbps Network Connections
Because the 10/100 port on the access point uses an MDI pin configuration,
you must use "straight-through" cable for network connections to hubs or
switches that only have MDI-X ports. However, if the device to which you are
connecting supports auto-MDIX operation, you can use either "straight-
through" or "crossover" cable.

N o t e
Pins 1 and 2 on connector "A" must be wired as a twisted pair to pins 1 and 2
on connector "B".
Pins 3 and 6 on connector "A" must be wired as a twisted pair to pins 3 and 6
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.
