Are app raspberry pi PoE safe?

[klintkrossa]

I have a pi supply pipoe. I have a inline PoE extractor.
I was wondering if all raspberry pi's are PoE safe?

check out the post in here regarding the device, I dont have one myself so i looked up this page which suggests its compaitle with the Pi-0, 3B and 3B+, https://thepihut.com/products/pipoe-swi ... spberry-pi

Isn't it a bit pointless to use a PoE on a A+, 3A+, Z or ZW as they don't have on-board ethernet.

Yes!, No!, it depends ....

on what you mean with PoE, is it a standard implementation or non-standard implementation ?

Right from its first incarnation the Pi has had an Ethernet connector with "magnetics" built-in - the signals are transferred via transformers, with no dc connection between cable and board.

So, provided the PoE system adheres to proper standards*, all Pis are safe.

* The dc supply must be between pairs - that is, one twisted pair carries the positive, another twisted pair carries the negative.
If a non-standard supply put both positive and negative on the same pair, the transformer would short it out, possibly destroying the Pi and/or the supply.

If I remember correctly, one test batch had the wrong connectors fitted with no magnetics. They had to have the sockets removed by hand and new ones put in. I don't think any of those went on sale, other than possibly at charity auctions.

Indded - that was a long time ago, and I don't think any of them ever made it in to the hands opf the public.
