RMB11G and HAP AC poe connection

Sun Oct 28, 2018 8:55 pm

Hello all.

I've one RBM11G installated on the Antenna pole connected actually to a Dlink router.

As i'm having some problems i would like to replace the DLink with the Hap Ac with POe in support like the rbm11g.

There is a way to use one poe power supply in between the ethernet cable used to connect the RBM11G to the HAP.?

May y use the mUSPS to do that?

Thanks in advance.

Maurizio

If you're going to connect RBM11G to ether5 port of hAP ac, then in theory you could daisy-chain power as well. Declared PoEout max current on hAP ac is 700 mA while RBM11G consumes max 11W ... if you go with 24V supply, PoEout current would be around 460mA. However, hAP ac itself cunsumes up to 17W which, combined with RBM11G, would mean max current around 1,16A ... which might be too much for PoEin port1 on hAPac.

I'm not 100% sure, never did try, bout you could try the following: use RBGPOE adapter on the tower to get DC out.
Then construct a Y-cable for DC current and power both devices (RBM11G and hAP ac) through DC jacks. Or a variant: use RBGPOE to extract DC and feed it to DC jack of hAP ac and then use PoEout (ether5) to power RBM11G through PoEin.

The basica variant of this idea would likewise work also if you're not going to connect RBM11G with hAP ac for ethernet connectivity.

Hi.

Just one question.

Isn't the WAN port the number 1? Connecting the RBM11G on the port 5 will work as well?

My ideas is to use one power supply only for both devices.

Do you think that one passive adapter like this will work?

Functionality of ether1 port as WAN port is by default. You're free to change that as you wish.

Personally I don't think the UBNT PoE adapters would work, the 24V models are rated up to 1A which is slightly too low.

Good Morning from Italy.

Yes i found on youtube how to change the wan port location.

I think i will move it to port 5 and then i will connect the HAP AC to an UPS system to protect both devices.
