I was handed a network that I am responsible for. I do not have a lot of experience with cabling which is why I am coming here for some advise.
I have ran some cable, eight runs which is connected to a Cat5e Patch Panel. I later tested those runs with a tester and wiremap and it came out perfect. All pares match up.
This is where my problem comes in, during some maintenance work I found that I had some problems identifying some cables (I did not run these cables and they are connect to a Cat5 patch panel, and it seems that we have a mix of Cat5e and Cat5 cables). The tools that I have also have some attachments that I can connect to jacks and using my main tool allows me to identify what office it is. Such as office 1 - 8 (note office 4 is also my wiremap tester) thus I can put these devices into jacks and go to the patch panel and make sure that they are linked to the proper location. I had four of these connections that I wanted to test out that leads to our computer room. I plugged in 1 -4 and started tested. three and four came out fine and I wrote down the port numbers on the wall plate but on the other two I started getting some funny errors. It seemed that both was showing as office1 and I was not getting office 2. So I switched to office three and it also showed up wrong. This allowed me to rule out bad hardware. I then took number 4 (which I have used a lot so I know it works) and hooked that up and it came out wrong. I switched over to wiremap testing and it showed that I had shorts in the cable. I am not sure which lines were shorted and I can retest if needed to find out and write back here.
So now to my question, after reading stuff on cabling I see that only the following lines are used 1,2,3, and 6 and I have to assume that they have to be connected alike at both ends. So if lines 4,5,7 and 8 were crossed with each other would that cause problems. The cable is working from what I see
What type of problems could I have? If 4,5,7 and 8 were crossed with each other would the cable still work at all? If these lines were crossed with 1,2,3 and 6 would the cable work at all?
Thanks for the help Adam Raff
