hEX PoE // Powersupply

Fri Sep 20, 2019 9:40 am

Hi everyone,

I've brought a hEX PoE Router. But I noticed that my PoE supported AP (AP130 from Aerohive) doesn't boot up. So I've connected a PoE Switch as the power supply for the Router and it works fine.

The delivered Power-Supply is a 24V 2.5A. I guess I need a better Power-Supply (like 48V 2.5A). Sadly, I have no clue about this stuff.

Can someone recommend a Power-Supply?

Thanks in advance...

Indeed you need 48V power supply. Any 48V power supply rated at least at 1A would do (but get some beefier one if this RB will deliver power to additional devices, up to 2.5A), just be careful about the DC plug dimensions. According to MT support, all routerboards feature same barrel-type power receptacles: 5.5mm outside and 2mm inside diameter, female, pin positive plug.

The hEX can't handle 48V.

Its PoE is passive PoE, not af/at. Take a look at the spec sheet:

... and doesn't do PoE out.

But OP mentioned hEX PoE which handles 48V and can do 802.3af/at on output.

Same thing, happened to me. I contacted support. They replied fast that I need 48V power supply. Strange decision from Mikrotik to bundle 24V with PoE router, but ...
So I bought http://www.wirmax.net/en/power-supply/6 ... apter.html. It's not original Mikrotik, but it cost me 14 Eur instead of 39 $.
So far, I've tested only with TL-POE10R PoE splitter and it's working. Next week I'll plug also Reolink IP camera, so I can give you update.

It is not surprising at all. I expect most people to be using this device to power other Mikrotik devices, and those are fine being powered by 24V Passive PoE.
