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 label on the switch, as shown in
Figure B-1
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.
