Wiring pinouts for ethernet cables
For standard ethernet network cable installations, use the wiring standards/ pinouts below.
To wire it properly, the wire being inserted should have the pinout numbered in sequence from 1 to 8 (left to right) with the modular plug’s gold contact side on the top, directly facing you (see top view of plug on the right). You will know you have positioned it the right way when the plug clip is on the bottom, facing away from you on the opposite side.
EIA/TIA 568B is used for Cat 5e/ Cat 6 network wiring and should be wired as such at both ends. Cat 6 cables are derived from the manufacturer’s cable specification (although the pinouts are the same).
To make a crossover cable, use the EIA/TIA 568A pinout at one end and the EIA/TIA 568B pinout at the other.
It is important to uniformly use the same standard throughout your network. If not, you may end up with some of the cable pairs crossed, causing data communication problems.
