cat5 Jack Pt. 2

[Ray]

I've installed tooless Cat5 jacks on both ends of my cable using the T568A convention;

PIN NUMBER COLOR

1 Green/White 2 Green 3 Orange/White 4 Blue 5 Blue/White 6 Orange 7 Brown/White 8 Brown

I purchased a Cat5e patch cord and noticed that these wire colors do not match my jack colors.

They are set up the following way looking left to right with the snap release pointed up and the connection towards you:

orange/white, orange, blue/white, blue, green/white, green, brown/white, brown

Is this a problem ?? I feel that if as long as there is 8 wires, regardles of the color coming out of the router, there is a path to send and recieve data.

Am I correct ??

Thanks, Ray

Electricity is color blind. As long as you know what is what it will be fine. The next guy will cuss you. But that is his problem

Your wiring for jacks is fine, but the purchased patch cord is not wired as T568A because #3 and #6 should be a color pair. Patch cords should be wired T568A and I'm surprised a purchased one would be be wired wrong. On a short patch cord it probably won't matter, and definitely won't matter on 10BaseT

I tested the 200' run of cat5 with the newly installed cat5 jacks by hooking up a laptop. The color coding for the patch cord did not matter as everything worked properly.

Thanks to all for your input !!!

You don't need all eight. Four will do. I forget which four.

Very true. IIRC, thats the diff between 568A and 568B. One of them (I forgot which) was designed so that the center pair belongs to one of the

2 pair sets and is not split. That way you can have network and phone in the same socket. The center two function as your phone line, and 2 other pair function as network, and 1 pair spare. Since RJ12 plug fits nicely in RJ45 socket. (it may be that both 568A and 568B do this, cant remember)

Or just split the pairs, 2 going to each socket giving you two network outlets, but then you gotta do your own scheme since 2 of the pairs will have to be mapped to the other color.

Pins 1-2 and 3-6 are used for the networking. The idea was that the innermost pair (4&5) would be used for telephone.

The only difference between 568A and 568B are that the orange and green pairs are swapped. A crossover cable has 568A at one end and 568B at the other.
