Crossover Cable:
When held with both ends as shown,
conductors up, the wire patterns are different.
Note the left plug – the order of solid wires is
orange, blue, green, and brown.
On the right plug, the order of solid wires is
green, brown, orange, and blue.
On a crossover cable, the pairs are designed to
“cross over” the signal when devices are
hooked directly to each other, instead of
through a network switch.
Devices area available with can plug into a cable and change the cable type from crossover to patch,
or the other direction. In the latest networks, the type of cable may not matter, as the system sense
the signal and corrects the pin signals as required. This is called “automatic MDI/MDI-X
configuration”.
Because of the many variations in network design, capability, permissions, and administration, a full
discussion is not possible in this manual. The field is very dynamic, and we recommend consultation
with network personnel on these issues if problems arise.
