Rules for Using Twisted-Pair Cabling to Network Computers
When you’re networking computers, running cable is not something you want to do more than you have to, so it pays to know the rules. These specifications are for networking with twisted-pair cabling:
Maximum cable length: 100 meters (330 feet).
All computers cabled to central wiring hub.
Terminators not required.
RJ-45 connector wired as follows:
Pin 1: Orange
Pin 2: Orange/white
Pin 3: Green
Pin 6: Green/white
Up to three hubs may be daisy-chained together.
Some hubs may also be linked using thin or thick coax.
To create a crossover cable, reverse the connections on one end of the cable so that pin 1 is green, pin 2 is green/white, pin 3 is orange, and pin 6 is orange/white.
