CAT 5 wireing confusion =)

[jl123]

I just got a crimper, jacks, and cable and I want to know how to correctly postition the wires in the jack. Here's one pic that i found on a website. They say that it is the industry standard.

But does it really matter what colors go in what pins? I mean just as long as they are the same on both sides right? I have some patch cables that i bought and they only have 4 wires not 8. Is there any diffent way of fixing the 4 wire cable compared to the 8 wire cable?

Here's the configuration of the 4 wire patch cables that I have.

Pin 1:Blue
Pin 2:White/Blue
Pin 3:Orange
Pin 4:None
Pin 5:None
Pin 6:White/Orange
Pin 7:None
Pin 8:None

Is this a correct configuration of the cable(4 wire)?

Please help me out on this one. http://sysopt.earthweb.com/forum/smile.gif

Well i got some of it. http://sysopt.earthweb.com/forum/smile.gif Ok so that picture that I posted, is it a patch cable or a crossover? I believe it's a patch but i don't remember the green wires being like that.

Why in some cables are there only 4 wires?

Here's another site with directions:

It has the same setup as the one you posted. Not all network operations require eight wire cabling, but many do. You won't find out which ones won't work until you need the eight wire cable and only have the four. A patch cable is set up like the picture. It's called that because it's used to "patch" a pc into a network or to "patch" a router into a patch panel. Dump the four wire cable before it causes you grief.

BTW, the image you have shows the setup from left to right starting at Pin 1 and looking at the clip from the bottom (the side w/o the retaining clip). Both ends of the cable should look identical when held side by side.

Joel,
The picture is correct. I've seen the four wire cables, too. The guy who installed my cable modem left me with one. THROW IT AWAY!!! It'll sort of work, but you'll keep running into things you can't do because the wiring isn't complete. If you're making a cable to run directly from your computer to a router or cable modem, use the example in the pic. Any cable that is attached on at least one end to a NIC or a hub/router/cable modem must be so configured. The only time your can use "straight through" cabling is to connect two points between network hardware. For instance, if you have a patch panel near your router and wall jacks near your computer, you can run "straight through" cabling between the wall jack and the router. However, the cabling between your computer and the wall jack must be configured as in the picture. The same goes for the cable between the router and the cable modem.

It's tough to explain. If I wasn't making myself clear, let me know and I'll try again.

Here is my favorite pic that I always refer to when I'm making cables. (this is for a crossover cable but if you want a straight-thru just do the first side twice http://sysopt.earthweb.com/forum/smile.gif )
