can passive PoE input be used as PoE output? hAP ac2

My connection to internet is done by a device that requires passive PoE (24V).
In-house WiFi is provided by a Mikrotik hAP ac2 tower (RBD52G-5HacD2HnD-TC).
Question: it would be elegant to use only one power supply for the 2 devices. When the ‘hAP ac2’ is connected to its power supply adapter through the round power connector, is then the 24V available on its Internet/PoE ‘in’ connector so that it can supply the device that receives the internet, so actually working as Internet ‘in’ / PoE ‘out’ ?
The current capacity of the adapter is sufficient to supply the two devices.

Since no-one has given you a definitive answer yet…

I would think it unlikely in the extreme. Supplying PoE (even passive, at least with MT) isn’t just a case of putting the voltage on the wires. It takes extra circuitry and options in the config. If the device could do PoE out as well as in on that port, it would be made clear as a feature.

No, hAP ac2 does not have PoE out functionality.

those power lines are not galvanically connected. to be honest, this is the ‘hidden dual PSU’ concept every mikrotik device (if equipped with PoE-in) supports.

  • you can power the box from the barrel jack and from the PoE in port simultaneously.

the device will chose the one with higher voltage and automatically switch over to the other one if the selected one fails in a hitless manner. no restart or glitch.
so you will not see voltage on the PoE-in port leaking to the outside.

Thanks for the clear answers. Having received the hardware in the mean time can also confirm experimentally that using the hAP ac2 as PoE injector from the DC connector to the first eth port does not function.
