Keep in mind most new Routers and Switches have auto sensing and do not need a crossover cable. In fact cross over cables will soon be outdated.
[Q] What’s the difference between CAT 5e patch cable and CAT 5e crossover cable?
[A] The difference has to do with the wiring of the cable and the situation in which you will use the cable.
On a CAT 5e patch cable, the wiring configuration is identical on both ends of the cable.
On a CAT 5e crossover cable, the wiring of pins 1, 2, 3, and 6 are “crossed-over” to pins 3, 6, 1, and 2.
CAT 5e crossover cables are used in situations where two devices have the same interface, for example, connecting a hub to a hub, or a switch to a switch, or even when patching a hub or switch into a wallplate.
The most common use is to connect two PCs directly to each other, without the use of any kind of router, hub, or switch. This is called a peer-to-peer network, and is a low-cost solution to allow file and Internet sharing between two computers.
