10/100 Straight-Through Pinouts

If the crossover function is implemented internally, the port is labeled MDI-X (Medium
Dependent Interface-Crossover). When an MDI-X port is connected to an MDI port, the
twisted pair media should be wired straight-through using the physical pinouts indicated in
Table C-2.
