Hex GR3 POE standards

Hi,

I’ve read somewhere (can’t remember where) that Mikrotik does POE differently? Reason why I’m asking is that I wanted to power 2 devices via POE as it will give me a better route for decluttering my cables. See attached image. My plan is to use the RGBPOE between my ISP provided modem and Mikrotik Hex gr3 ether1. The Hex in turn will be used to power the TPlink OC200 via ether5. The stock power adapter that came with the hex will be used for the RGBPOE. The rest of the hex ports will be used for my Proxmox lab (ether3) server and AP (ether4).

With that setup in mind, any risks of toasting something or something not powering up?

Why don’t you read the documentation and device specifications for each device mentioned by you above?
Instead of relying on “something” that you’ve read “somewhere”.

I think I may have made a mistake… hex gr3 doesn’t have POE out… should have been hex poe (not lite).

Also, the PoE ‘out’ is never 802.3af/at, so that would not work anyway. The PoE out is always ‘passive poe’, which is sometimes all that they support on PoE-in as well (some devices support ‘real’ PoE on input though).

incorrect there are af/at compliant devices, example: https://mikrotik.com/product/rb5009upr_s_in
Hex S supports passive up to 57v most of the PoE in af/at devices will support passive in as long as the correct voltage is applied, ie hex S at 24 volts wont work but a hex S at 48v will
