10/100 Ports

The Cisco ME 3400-24TS 10/100 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-1shows the pinout for a 10/100 port.
