Identifying a Crossover Cable
To identify a crossover cable, compare the two modular ends of the cable. Hold the cable ends
side-by-side, with the tab at the back. The wire connected to the pin on the outside of the left plug should
be the same color as the wire connected to the pin on the outside of the right plug. (See Figure B-13.)
