10/100 and 10/100/1000 Ports
The 10/100 and 10/100/1000 Ethernet ports use standard RJ-45 connectors and
Ethernet pinouts with internal crossovers. These ports have the send (TD) and
receive (RD) signals internally crossed so that a twisted-pair straight-through
cable and adapter can be attached to the port. Figure A-3 shows the pinout for a
10/100 port.
