Straight-Through and Crossover Cables

To tell whether your cables are straight-through or crossover, hold the ends of your cable side by side, with both spring clips facing down.

Straight-through cables have the same order of wire colors in each tip, when held side by side. Most connections use a straight-through network cable.


Crossover cables, on the other hand, show different wire colors when held side by side.


If you are using homemade network cables instead of the store-bought variety, make sure that your RJ-45 ends are securely attached, and that your wires are properly pinned out according to the diagrams above.
