Switch – Patch panel problem

patch-panelswitch

We have a couple of ip cameras. The company who delivered those also made the UTP cables. They had them directly in the switch. I now changed it to go trough the patch pane, but i just can't get a few of them working. We use the T568B configuration. But after checking the utp cable at the camera i noticed that they made the utp cable like this:

brown – brown/white – green – blue/white – blue – green/white – orange – orange/white

How do i put them in our patch panel?

I tried to reverse(Brown in blue/white in the patch panel etc.) them (since they did the cable the wrong way), but with no succes. I tested it with our cable tester and the LEDs just went from 6 to 3 etc.

The correct answer is you don't "fix" it at the patch panel. If you follow the code and it doesn't work, you need to fix the other side.

One of the reasons people use T568A/B and not any straight through wiring pattern they want is that it makes troubleshooting and repairs much simpler, as you are finding out now. If you don't fix the other end now, you will be in the same situation (or someone else will) 5 years from now while trying to fix the camera side of the cable.

I also firmly believe that infrastructure cabling should be infrastructure cabling, not a "long patch cord" running through a building. So I would terminate the camera end of the cables to a jack and use a patch cable to connect the cameras.

If you really must take the shortcut (for instance, it is more important to get the camera up ASAP), then you can do so, but put this on your priority list of things to fix ASAP. Just "reverse" where you punch down, since brown is where white/orange should be on the far end, punch it down where white/orange should be. White/brown to orange, green to white/green, and white/blue to blue.

I also recommend that you develop a cable standards document detailing how you expect cabling to be run for your organization and provide it to any contractor working at your site. Then enforce the document before you allow them to get paid.
