help with 16 port hub to jack problem

I am an experienced ELECTRICIAN who sometimes doubles as a low voltage
installer.

I have encountered a problem I need some expert advice for.

In an office that had a "messy" network with the cat5 hanging out of
the ceiling panels I have fished the cat5 down the wall into HUBBELL
jacks.

Trouble is I plug the computer into the new jack and I do not connect
nor do I see the network. All the lights are OFF.

I redid the jack 3 times, made 2 new patch cables, ran a new cat5 to
the HUB (a 16 port SMC).

If I connect the cable from the HUB directly to the computer (with an
RJ-45 end) it works fine. If I chop off the end and terminate to the
jack and plug there, NOTHING!?

Please help, this is my wifes place of employment and I'm looking
stupid on this deal and I'm frustrated to the point of calling in
someone to fix it at my cost. I spent 5 hours on one office and have
more to go. This is going to be a big loss for me if I don't get help.

What type of cable from the jack to the computer should I be using?
Shouldn't this be a straight through cable?
I don't need a patch panel to do this do I?

Is the pin-out diagram on the jack to be used from side look or the
alternate pin-out?

Help me I'm going nuts.


Thanks,

Roscoe
 
there's "A" & "B" wiring, which one are you using on the jack? and which one
are you using on the rj-45 head?
 
DONE!

The fellow who originally did it, wired it to 568B but REVERSED clip
up 8-1. I should've peeked at the HUB end when I was having all the
trouble..

I talked to him and he laughed and said "as long as it's all the same"
All well and good if nobody else does any work there and you don't try
to put any new jacks with proper color codes.

Drove me nutty.
