hAP-ac^3 PoE-in: which port?

Fri Jul 01, 2022 2:21 pm

Hi all,

Simple question: which port can I power the hAP-ac^3 via PoE-in?

I can't find anything in the documentation.

I tried ports 1 and 5 (and 2 and 3 for good measure), both with and without the DC jack plugged in. But it never turns up if the power's off or the DC jack is out.

On the other side of the switch is an 802.3af/at switch: a TP-LINK TL-1016pe, and the switch is connected to one of the PoE ports of the switch.

What port should I use for this to work or (alternatively) what am I doing wrong?

EDIT: You can only use the provided injector. This device will not work from a TPLink switch. It does not have support for 802.3af/at, only Passive PoE

On port eth1 it says PoE In, so my assumption would be eth1.
Make sure you use passive PoE:
PoE in input Voltage 18-28 V

Mmm...I should refresh before posting...

🤦 thank you, so port 1 only. The router is mounted at height, and the ports are facing up, so couldn't see that...

Oh, that's a bummer... I did not get an injector with mine, just the wall wart that is currently powering it. Is this something that should have been in the box, but might have been forgotten, or does the packaging vary by region?

I do have a few cheap 802.3af/at splitters, but they force the link to be 10/100 rather that gigabit, so it's not great.

Does the Mikrotik injector let the port work at Gigabit speeds, and if so, where/how could I get one?

Wow, the doc got updated quickly! https://help.mikrotik.com/docs/display/ ... g-Powering

It might be worth mentioning the lack of support for 802.3af/at, and the need to use the provided injector.

The product page always listed
PoE in Passive PoE
PoE in input Voltage 18-28 V

There's no reason to try powering it with something else.

But what is stamped on the chassis is already there when you buy the device: PoE in on ether1 and DC 12-28V


It might be worth mentioning the lack of support for 802.3af/at, and the need to use the provided injector.
But more than anything else it is you who should not make assumptions, if it is not written, it is not written!!!

This device does not come with an injector. Only the Wallmount and outdoor WiFi devices do.
You can buy it separately as an accessory and use it with the supplied wallwart.

RBGPOE, or depending on the network setup , you might consider having an RB260GSP , hEX PoE, Powerbox Pro, or other MT device with PoE out as part of the network, that could power it.
Nicer cabling if you have to combine SXTsq, wAP ac, hAP ac2, cAP ac, etc etc. And end up with a lot of spare RBGPoE :-) .

support for 28volt already suggest No 802.3 standard PoE support because standard operate at 48volt

Sadly vast majority if users are not aware of differences in various PoE dialects ... and since many (probably most) vendors nowdays support 802.3 af/at/bt/... one can't blame people to assume ... so clear marking "no standards compliant PoE inside" would make sense.

Yes, it is actually surprising that this new device does not support 802.11af/at. Maybe it was designed to a price point for home usage as a central router.

In turn I was surprised that an old wAP (not AC, just the 2.4GHz N type) does support 802.11af/at. I had installed it for testing at work, plugged the inserter between the 802.11af/at compatible switch and the patch panel in the server room expecting it to be required, then I wanted to move it and connected it to another wall outlet and thus switchport, and it immediately started to work again. I had expected to first have to move the inserter, but no. And is a $45 MIPSBE device 5+ years old.
