10/100 Ports
The 10/100 Ethernet ports use standard RJ-45 connectors and Ethernet pinouts with internal crossovers,
as shown by an X in the port name. These ports have the transmit (TD) and receive (RD) signals
internally crossed so that a twisted-pair straight-through cable and adapter can be attached to the port.
Figure B-1 on page B-2 shows the pinouts.
