I have a hAP ax², that I would like to power via the switch. My switch is a LINOVISION industrial switch.
I can NOT for the life of me, figure out why I can’t get power to the hAP ax2??
This is the switch:
Switch powers my router already.
hAP can be powered via an external PoE power unit.
Both devices are working, and they don’t work together!.. weird.
Thanks
From the product specifications:
Passive PoE is not that standardized as 802.3af/at. Your router probably supports 802.3af/at.
Yeah.. Since my switch can no longer be purchased, Im thinking that it has some issues, and It looks like I just found one of those issues.
Looks like there is a newer product too..
Whats your take on the newer one?
Probably won’t work either as the hAP ax2 can only be powered using passive PoE as mentioned above. That switch will only enable PoE when it sees a device supporting 802.3af/at (active PoE). Doubt it would negotiate PoE at all. That's my understanding. Just use the power supply?
Well, that sucks. I’m using this in a Van. 120vac is only available on demand. 12vdc is possible. I’m just trying to power network parts, using the PoE that’s made for running 12dvc.
ps. I’m using the Mikrotik as a AP only for WiFi6. Might have to abandon this idea, and go with another route for an inside AP.
Thanks
That linovision has 12 V input, but has 48V (conventional) 802.3a Active PoE out.
You can get a splitter/converter, 802.3/at compatible, converting to 24 V and Power the Ax2 via jack.
A device like :

Could you use a hEX PoE switch instead of the LINOVISION? Appreciate it’s not an industrial unit.
No, the hap Ax2 Is (PoE) 18-28 V, the hex poe Is 12-57 V.
If the available voltage Is theoretical 12 V ( more likely 10.5-14V) It Is barely enough to power the hex poe but there Is no way without a step up converter to reach the minimum 18 V the Ax2 requires as PoE in.
But It could be powered directly via jack adding two wires.
Ahh, I wondered if it was like the cAP ac which can use both passive and active PoE input on a much wider range of voltages, up to 57V.
Another possible approach would be to raise the voltage powering the hex poe to 24V and then use PoE out passive to power the Ax2.
But OP already has the Linovision and using a splitter/converter Is also the cheapest possible solution.
Well.. Im perplexed at which direction I can go from here.
Currently, I have a LINOVISION industrial switch, which powers my Peplink router in a small system on my Van.
I wanted to add in a AP for running another WiFi inside my van. I decided to use a Mikrotik HAP AX2 and turn it into just an AP. I set this all up, but I can’t power my HAP AX2 now because the LINOVISION is not correct.
Can I swap to another POE switch like this?
In order to run both Peplink and the HAP AX2 from the same switch?
.. and, if I use this, I’ll have to go 24vdc anyway??
Is there another product that I can use as an AP using this PoE switch?
Why cannot you use the simplest solution, a splitter/converter?
power converter?
I’m really went to my limit on power in this Van. I have over 50+ DC power runs. Each new power supply, draws another 5W or more… I’m trying to ulilize what I already have, without re-inventing the wheels.. 
This whole thing is to get a single networked server device, into my network that will NOT connect to my current WiFi (no one knows why). Next thing I know, I’m thinking of setting up a secound WiFi AP just to connect this deivce, and next thing you know, I’m going well over my power limits with watt draws. humm..
ps. I just thought of something, since I have a RasPi running on this network, perhaps I can just activate the WiFi on that RPi and connect my device.
Each solution I come up with, is met with something that goes over my spending, goes over my power requirements, or is NOT reliable. lol
I think I didnt understand what the splitter/converter did… It actually doenst plug into a power source, but it plugs into the thing your trying to power??
There's no perplexing to be done You can get yourself a proper poe (af/at) AP, such as a cap ax or wap ax (the latter I can image for your application), or just supply the ax2 with the battery 12v on its dc plug. They tolerate the automotive range fine.
EDIT: 12V over twisted pair is generally a bad idea. An af/at to 24V converter doesn't consume much power, but if you're trying to minimize power, then go for ac rather than ax devices. Ax access points draw quite a bit more power and Mikrotik's ac stuff is really cheap and easily available.
Your Linovision has 12 V input.
It converts It to 48 V 802.3/af or /at PoE, over the ethernet cable.
On the other side of the ethernet cable you place an 802.3 PoE splitter converter that negotiates with the Linovision to get the 48 V, then converts It to 24 V that you get on the DC jack that you can use to power the Ax2, as if It was its original mains power adapter.
The data (without any DC voltage) will be on the RJ45 plug of the splitter, that you can connect to one of the ethernet ports of the Ax2.
This Is the less expensive solution, as you already have the Ax2 and the Linovision (this latter already installed).
Otherwise, since It Is a van, not a cathedral, the Ax2 Is largely overpowered, if 2.4 GHz Is enough, you could consider a mAP, very small, 802.3/af compatible (no need for the splitter).
COPY! Nice. Thank you.
Yes, I know the ax2 is way too much for a 20sf space.. So, this mAP with just 2.4 sounds like it’s good enough for this set up (connecting things like A/C, heater, Victron, KINCONY Home Assistant). Nice!
Thanks, I have a plan now.
Why did no one recommend swapping the hAP AX2 for the wAP AX?
Especially inside a VAN…
