So I wired a bunch of outlets in my house for cat6. I have a nice little patch panel with maybe 16-20 cables going to it.

Unfortunately, I did not label anything… an oversight which I would like to address now.

I have this basic cable tester that sends an electric signal sequentially to each wire of a cable, ligthing up LED on the other end. I do not have a probe/toner kit.

I was planning on using that LED tester to identify what outlet correspond to what port on the patch panel.

Now, it would definitely take less time to unplug everything from the patch panel and test safely. But I needed to know: can one of those tester fry equipment?

Say I plug it into a wire that goes into my top of the line, unamanaged, was the cheapest rackmoutable option, gigabite, TPLink switch. Is it: A) known to be safe, B) “Ish” probably fine but sketchy territory or C) definitely will fry the switch.

Thank you :)
