pinout for cross cable:

one end:
1,2,3,4,5,6,7,8

the other end:
3,6,2,4,5,1,7,8


where 1 is orange/white striped and 2 is orange and
3 = green/white striped
4 = blue
5 = blue/white striped
6 = green
7 = brown/white striped
8 = brown


Basically this switches the input and output channels. Usually hubs and routers have a crossed port already, where it's crossed in the hub/router itself. [this is useful to connect multiple hubs/routers to eachother using a normal [straight] cable]

Cheers.

Another way to think of it is to have a 568A connector on one side and a 568B connector on the other. A google search will turn up how to setup the wires for those standards.

what's on pin 1 on one end is on pin 3 on the other, what's on pin 2 on one end is on pin 6 on the other, the rest all go in the same order

NovaFlash here is what yours should say as 1 switches places with 3 and 2 switches places with 6.
NOVA said
one end:
1,2,3,4,5,6,7,8

the other end:
3,6,2,4,5,1,7,8

He should have said

one end:
1,2,3,4,5,6,7,8 (1)Orange-White,(2) Orange, (3)Green-White, (4)Blue, (5)Blue-White, (6)Green, (7)Brown-White, (8)Brown

the other end:
3,6,1,4,5,2,7,8 (3)Green-White,(6)Green,(1)Orange-White, (4)Blue, (5)Blue-White, (6)Orange, (7)Brown-White, (8)Brown

 

by: pbessmanPosted on 2003-07-08 at 22:53:36ID: 8882717

I goofed! It should read:

the other end:
3,6,1,4,5,2,7,8 (3)Green-White,(6)Green,(1)Orange-White, (4)Blue, (5)Blue-White, (2)Orange, (7)Brown-White, (8)Brown

pbessman should get the points though. That was the correct answer.

 

by: pbessmanPosted on 2004-05-19 at 06:56:04ID: 11107897

Yeah! What about me?

 

by: MarkJenksPosted on 2004-05-24 at 08:34:43ID: 11143957

So with all of the valid answers and links to websites, your going to say that no one gave a good enough answer?

 

by: pbessmanPosted on 2004-05-24 at 11:50:16ID: 11145675

I don't think he /she is watching their question.  I am wondering if the code in question is when to run plenum and when not to.

Hello All,

Actually I though all the answers were valid and very good, but the Q only offered 30 points, so I couldn't split it between you all. Thus a PAQ unless someone objected.

And you have :-)

I will leave the following recommendation for this question in the Cleanup topic area:
