Re: Dumb things you've done on a computer

Speaking of POE, while I've installed a fair share of network jacks in my home about 7 years ago, recently I've moved to POE for my cameras.

I re purposed some of the drops in my home that were not being used for the new hikvision cameras i had and purchased a rack mount injector for the network:

»www.amazon.com/WS-GPOE-1 ··· rds=rack mount+poe+injector

While i had no issues on the rack side moving cables over, the ends on the cameras needed to be cut and crimped.

Lets just say it took about 3 times before i remembered to power off the injector before cleaning up the ends on the cable...nothing like sparks at the jack, an alarm from the APC UPS freaking out, and my dog crying because who knows what sounds that thing made when clipped.

TL:DR - Dont terminate POE drops while powered.

I am glad I am not the only one who has made errors with PoE. I am wondering if you can actually fry a jack along with the device that is plugged in.

Me yesterday. "Alright, this cable is connected to the patch panel", plugged it in to the tester and the lights go nuts before I even turned it on, look over and see it is instead connected to the router. Oops. Ubiquiti is not kidding when they warn you about it potentially damaging your device.

Tester got a voltage it certainly can't handle.
