I am a technician trying to venture forth beyond Desktop troubleshooting and into networking issues.

The company I do IT work for has around a dozen cubicles that each have 2 data ports, which are not labeled accept for the 'D1 and D2' labels letting you know that they are data ports.

I tried to setup a laptop in one of the cubicles and the D2 port was not active, only D1. I went to each cube and found only 3 cubicles had the second data port active.

In their server room, nothing is labeled (I should say, this company had a different IT company providing support for them, then we picked them up, so we did not set them up without labeling anything in their server room).

Anyway, there are 3 switches and I am not sure which switch port is associated with what data port in on their main floor.

Other than tracing cables, which would be a full day project since this company is huge and cables run everywhere, is there a way I can identify which switch port goes to what data port for each cube?

How are the hostnames configured some times network engineers and desktop techs configure the hostname to reflect connection on networking devices like workstation1_fa34 would be workstation 1 on fast ethernet port 3/4.

You will need to get something like this: http://www.cablestogo.com/product.asp?cat_id=1423&sku=26847

No, the hostnames just reflect OS and username..example wxp-jjohnson.

I will look into the device.

If a cubicle has two data ports one might be for the phone.

you can use something tons cheaper like this :
http://www.newegg.com/Product/Product.aspx?Item=N82E16812998083

Plug one end at the outlet then head to the server room with the other end. Just plug stuff in until you find a winner. Then be SURE TO LABEL THEM, unlike the last guy....

You can buy a variety of cable tracing devices. Be sure to use one which is ok on a live ethernet port unless you intend to shut down the entire network to trace the cables. www.blackbox.com/resource/files/productdetails/26813.PDF

If you don't want to spend a lot of money and shutting down all the switches and computers is an option, you can buy a cheap tone and probe from harbor freight tools. I would NOT use that on live cables.
