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 .)
