Trouble POE port 5 from MikroTik HAP ac Lite do not power on Powerbeam M5

Hi everyone,
New to AREDN I just bought a "MikroTik HAP ac Lite" router and a Ubiquiti Powerbeam M5-300.
The router is flashed with firmware AREDN 3.23.8.0. The antenna is not AREDN flashed, just updated to the latest Ubiquiti firmware (XW.v6.3.11 Build Number: 33396)
With the POE adaptator included, the M5 power on
But if I connect the M5 to the port 5 "POE Out" of the router, it does not power on (no LED on).
I've tryed with router
a) powered throug POE on port 1
b) powered through AC adapter
c powered with a) and b) toogether
No one allow the M5 to to power on ;-(

My goal is to be able to operate a mobile AREDN station, with only a 12V power supply

Any suggestion ?

Many thanks Chuck ! This
Many thanks Chuck ! This setting was not ON by default, and after activating it the POE work :-)

Mikrotik hAP ac Lite: POE Power Options
You will need a 24 volt power source to properly operate the units.  This can be accomplished with one of those inexpensive step-up power converter boards.  Although the UBNT device "can" operate down to 10.5 volts, the power losses in any significant length of cable will put the far end near that level fairly quickly. Not sure how far down the HAP will operate, but best have something in the 22-24 volt range to start with.

Hello,

Hello,
You say you want to run the entire thing from 12VDC.  The hAP might boot on 12V but I doubt the antenna will.  The POE in the hAP is pass thru so what you give the hAP is what the antenna will see.  The optimal voltage is 24VDC so you need a boost converter before the power injector.

Some of the newer hAP have been giving folks problems but if you do like Chuck says in settings, and power the hAP with 24V then the antenna should be happy.  If not, it's easy to split the 24VDC and put one 5.5mm into the hAP and use an inexpensive DC power injector to get power to the antenna downline from the port on the hAP.

PS that's funny we both posted same time.  Here's an example

Thank you Ed ! After I set
Thank you Ed ! After I set the POE option to ON, as suggested by Chuck, the POE work, and the antenna too :-)
But the Hap is currently powered through the 24V adapter. The voltage of the POE output is power IN minus 2 V, also if I connect it on a 12 V battery, ther will be  only 10V POE output. So I will need a DC 12V to 24V converter to power the hap and then the antenna through the POE. Thank you for the Amazon link :-)

antenna?
What device are you referring to as 'antenna' ?
IFAIK, firmware cannot be loaded on an 'antenna'!

All of those devices are

All of those devices are shipped with a 24v AC adapter, but they will all operate fine on Passive PoE within a range of between 12v and 24v.  You can run the Powerbeam from the PoE port of your Mikrotik hAP ac lite without any issues.  You can also power it in the field using a 12v battery.

Hi, Ed:

Sorry, it is a fault of mine.
I do try to avoid pronouns when who is doing what with which and/or to whom,
might get misread.

Eschew obfuscation, espouse elucidation.

Missing from my previous post was the smiley

I'm a difficult person in my own unique way and understand completely.  Precision is a lost art in this day and age, so your efforts are noted.

You said you are using stock
You said you are using stock Ubiquiti firmware in the PowerBeam.  Good bet that is not going to work.  The reason is the port 5 on the hAP is expecting a device that is flashed for AREDN and using whatever protocol that AREDN Device to Device (DtD) uses.  The PowerBeam with non-AREDN firmware will have not idea how to communicate using the DtD firmware.

Obviously the problem goes away if you flash the PowerBeam for AREDN

The one I don't know is if the other end of the PowerBeam path is also using Ubiquiti firmware and the two devices can be made sufficiently transparent to the traffic passing through them such that another AREDN device that has it DtD port connected to the far end Ubiquiti microwave path - essentially making the two AREDN devices appear to be directly connected to each other.  Then it may well work.
