Port and Cable Assignments

Straight-Through Wiring

If the twisted-pair cable is to join two ports and only one of the ports has an internal

crossover (MDI-X), the two pairs of wires must be straight-through.

Crossover Wiring

If the twisted-pair cable is to join two ports and either both ports are labeled with an

“X” (MDI-X) or neither port is labeled with an “X” (MDI), a crossover must be

implemented in the wiring.
