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 a different color from the wire connected to the pin on the inside of the right plug. (See Figure B-10.)

Figure B-10 Identifying a Crossover Cable

Pin 1 on one connector and pin 1 on the other connector should be different colors.
