I have problem PoE with my router MIKROTIK ROUTERBOARD RB962UiGS-5HacT2HnT.
On the Mikrotik console I set the PoE Out to "Auto On" and also on "Forced On", but still nothing on the my camera Dahua IPC-HFW1420SP-02880B, 12V , 0.5A.
Did I set something wrong ?
I connected the poe tester FLUKE networks or Cisco Phone 7841 and nothing.
There seems to be no poe on ether5.
How to check the operation PoE?
Thanks.

Thanks for the detailed post!
This routerboard (hAP AC) supports passive PoE only.
Dahua camera on the other hand, requires Active PoE (802.3af) according to its specs.
If this is your only camera, the cheapest solution would be to purchase a standalone Active PoE (802-3af) injector, have seen UTEPO UTP7201GEPSE30 used with these cameras.
If you plan to add more cameras, then I would consider getting either an hEX PoE if you plan to install it indoors, or a PowerBox Pro if you'd prefer to install it outdoors.

Re: RB962UiGS-5HacT2HnT (hAP ac) problem with PoE!
if I plug in this power supply "MikroTik 48V 1.46A", I'll have passive poe 48V ?. That's gonna work with the camera?
I've got 22.5 V at "ether5" exit.
Then why is this Poe passive? What devices can I power?
I thought this "hap ac" supports "802. 3af"
Thanks.

Hi.
I had a very similar problem to yours.
The output of the POE port will be the same as the input of the mikrotik. So if you are plugging 48V to your mikrotik it will output 48V on POE. Recently, I tried to power on my Raspberry Pi with a POE hat, which is also 802.3af. My problem was that the input of the power supply was 24V and the POE hat needs 37–57V. So what I've done is replace my power supply with a 48V one and everything "worked". Well, the Raspberry is working, but from time to time the RB4011 just randomly reboots.
Basically, you need to make sure that the input voltage of mikrotik matches the necessary camera voltage.
Regards.

Re: RB962UiGS-5HacT2HnT (hAP ac) problem with PoE!
Standard for PoE (802.3af/at/bt) requires some (pretty simple) "data" exchange between PSE (power provider) and PD (power consumer) for PSE to start providing power. Passive PoE OTOH does not, PSE simply provides power and PD can take it (or not). Due to simplicity of 802.3af protocol, sometimes things work if PSE is passive while PD is 802.3af as long as PSE provides voltage within 802.3af allowed range (37-57V). It can't work if PSE is 802.3af and PD is passive because PSE does not provide power without first exchanging "data" with PD.Then why is this Poe passive? What devices can I power?

No, hAP ac is passive PoE capable. It's upper voltage limit is within 802.3af range, hence above described scheme might work if hAP ac is used as PSE.
