How to find errors in a cable in the LAN?

2020-11-25 06:05:52

Hello, I have installed 5 cat7 network cables in the house. All start in a patch panel and then go to the network sockets.

The problem now is that one does not work. I have already replaced the socket once and connected it to another output in the patch panel. Each time the tester shows that Channel 8 does not work.

How can the cause be found here?

Do I understand correctly that you have already swapped the modules at the ends of the cable in question? Or, as it reads, you are using a punch down tool. Are you sure the wiring is correct? If you have empty conduits, replace the cable. Otherwise, check with a good tester. The location can then be identified by tones. Ultimately, this also means that the cable must be removed for repair. A new cable is easier...

Can I possibly test something with a multimeter? I would prefer not to change the cable.

Laid cable or with Keystone?

Of course you can do that. Just measure each wire at the open ends. If all have "continuity," your problem is not with the cable.
