The shell for each connector is connected to the chassis ground. The 100Base-TX ports have their transmit (TD) and receive (RD) pairs internally crossed (shown with an x) for attachment to an adapter using a straight-through cable. The straight-through and crossover cable schematics are shown in Figure B-3 and Figure B-4.
