Plugging non-PoE Devices Into PoE Switches: Will It Go BANG? (Power over Ethernet Dos & Don'ts)

- I've recently purchased a bunch of Power over Ethernet (PoE) cameras for my home's security system, and so I started looking into powered network switches - in other words, PoE compliant switches. But are they 'safe' to use? After all, they send electricity down the Ethernet cable?!
And what happens if you accidentally plug in a normal (non-PoE) device into a PoE switch?
I explore all this - and more - in this video... including via a VERY suspect looking demo! I combined TWO power over Ethernet switches with three non-PoE devices (a HP printer, DVD player and TP-Link Gigabit switch), and turned it all on!
The individual sections of this video are:

00:35 Sketchy Demo
01:30 How PoE 'Should' Work
02:26 Passive PoE

This video answers a question that I was way too lazy to google
This is the way 😆👍
Thanks.... I always wondered
No worries 👍
Yep, I was also wanting to know the same. Just bought a new Netgear POE switch for 7 new POE cameras (and ethernet around the house whilst I was at it). I just wish I had come across this yesterday before I said "Oh well, let's see what happens" 🙂 I can now keep my old switch with my home and work computers with only 1 trailing cable whilst I set up all other stuff and wait for the new data points in the office and move everything over to the data rack.
That sounds like it'll be a sweet setup (I have 7 PoE cameras streaming to my NAS, it works out great). Glad you liked the video and good luck with your networking 🙂
Most poe switches auto sense , unless its passive poe like those 24v gen1 unifi switches where u can turn the power on on the switch port and leave it in the on position
This is a good/necessary feature for sure. The 'always on' options can make sense, but scare me so I tend to avoid these type of ports/switches 😄
Many injectors are passive PoE. You also have to consider voltage. Some devices will not work with the 24V injectors.
Hmm that's true, I actually have an active PoE injector somewhere, but you're right that many aren't. Good point thanks 🙂
