I mean, the simplest answer is to lay a new cable, and that is definitely what I am going to do - that’s not my question.

But this is a long run, and it would be neat if I could salvage some of that cable. How can I discover where the cable is damaged?

One stupid solution would be to halve the cable and crimp each end, and then test each new cable. Repeat iteratively. I would end up with a few broken cables and a bunch of tested cables, but they might be short.

How do the pro’s do this? (Short of throwing the whole thing away!)

My TP link switch can detect faults and cable length. I’m not sure it can do both together but it’s possible. Worth checking if you have a switch with those features

Hmm, interesting! I have a Synology switch, gotta read up on its capabilities.
