What is the exact configuration?
E.g.:
Switch[Ethernet port] <[Ethernet plug T568A or T568B]------Cat5e cable ------>Keystone (T568A or T568BA)?
Or by "switch" do you perhaps mean "patch panel"? Either way - any make and model information?
And by "got nothing" I believe you mean no network connection. What about the physical continuity between ends?
All too easy to also get the plug and jack orientations reversed.
Can you offer more explanation? Thanks.

Sorry, I'm not very good with the technical aspect as I usually have always had crash courses in networking cabling. But yes the one end goes into a Leviton Power Sum Category 5 patch panel (not sure of the exact model as there are no other numbers listed anywhere on the unit itself). The other end i have run to a wall box with a Cat5e Keystone jack.
Cisco Catalyst 2960 series switch ---> Leviton Power Sum Category 5 patch panel -----> Cat5e cable ------> Keystone wall outlet (basic Monster brand from HomeDepot/Lowes)
This is where I am having the issue. I can't figure out the actual numerical order to the wires.
The exact wire configuration coming from the patch panel is, in this order from left to right:
Blue/White
Blue
Orange/White
Orange
Green/White
Green
Brown/White
Brown
As there are no numbers listed on the back of the panel i am assuming these are 1-8. So I attempted to duplicate that on the keystone, but with no working results. I only have the computers present to connect to check the working/not working of the outlet. And I get no connection.

Even if you were to duplicate it the pairs are wrong. The wire color does not really matter it is just colored plastic. Keeping the wire pair correct though is critical. The signalling is very dependent on the wires being twisted together from each pair.
The pairs are 1,2 3,6 4,5 and 7,8 Your cable has the wires from different pairs connected to the pins in the middle 2 pairs.

I googled the patch panel - T568A per the following link:
http://www.sasanelectricals.com/leposumcat52.html
If the link does not present your patch panel then use the product description/UPC found on your patch panel.
As for the Monster brand Keystone outlet there are small colored decals on the sides.
One row is for T568A and one row for T568B as shown in the following link:
http://www.acehardware.com/product/index.jsp?productId=29315126
The blue and brown decals are on the other side.
So the punched in color wiring pairs should, on both sides correspond with the A decals. Blue wire punched in where the A blue decal is located and the Blue/White wire punched in where the A Blue/White decal is located. And so on for the other three pairs. The punch down locations are what match wires to pins.
Are you doing your own cable terminations: i.e., the male plugs on the ends of the Cat5e patch cables between 1) switch and patch panel, and 2) wall jack and pc?
You must be sure that the plug is oriented correctly (tab up, tab down, facing you, facing away) to get the wiring pairs in the proper order. Otherwise you can reverse the pairings. Look very closely at the diagrams to verify the orientation before inserting and crimping the wire pairs.
Google "Ethernet wiring schemes". Many examples, diagrams, etc. to be found.
The objective is to ensure that you are using a consistent scheme. Once the scheme is established then any further problems are likely to be from incomplete punch downs or plug crimps.
