Straight-Through Wiring
Because the 10/100 Mbps 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.
Crossover Wiring
Because the 10/100 Mbps 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.
