hello. cat5 utp uses the wires for 1-2, 3-6, where '-' denotes a pair, not
a range as in 3 to 6. wires 1 and 2 should be one twisted pair, 3 and 6
should be another twisted pair. if you look at the diagram below,
orange/white and orange make the 1-2 pair, and green-white and green make
the 3-6 pair. the nice thing about following said standard is even if you
do the reverse and count from the bottom, you still get the 1-2, 3-6
pairing.
if you want a cross-over cable, like for connecting two ordinary hub ports
or two computers together, you'ld want to switch the pairs 1-2 and 3-6
where the 1-2 pair on one end is the 3-6 pair on the other.
hope that helps.
vince.
p.s.
you know, come to think of it, these are the things you have to learn
along the way with being a sysad. i mean, when i started, i never really
cared about cables and stuff. i just wanted to create some useful
rock-solid servers. but i didn't want to bother our tech guys so much so i
had to learn it myself. the same thing goes with opening up
computers. well, just sharing some pleasant realizations. =)
