AD380A and AD381A Installation Guide

Figure 2-2 10/100 pinouts using external crossover through twisted-pair media
Gigabit over copper pinouts using internal crossover
Unlike connections in which the crossover function is implemented internally at the hub or
switch, the AD380A provides its own automatic crossover function. This means you can wire
twisted-pair media straight-through for adapter-to-hub, adapter-to-switch, or adapter-to-adapter
connections using the pinouts indicated.
