I just wanted to share this nugget of information with my fellow Meshers.

Ubiquiti Network POE adapters are not compliant with the IEEE 802.3af standard.  I'm not sure if their equipment is compliant either.

The difference? IEEE 802.3af is a 48 VDC POE standard whereas Ubiquiti Network products use a 24 VDC POE.

When you purchase equipment which is IEEE 802.3af compliant, that equipment will not work using a Ubiquiti manufactured POE adapter. You will need to purchase an IEEE 802.3af POE adapter to power the equipment.

73 and keep meshing

Correct,  Ubiquitit does not use Active PoE (802.3at/802.3af) it uses Passive PoE (a common industry practice) as noted in the datasheet which is simply sending voltage up the spare pairs that are not used for data and essentially turns the cable into a long extension cord + data pair

This mostly has advantages on manufacturing side where it would cost a couple bucks for the PoE chip on the receive side and again on the power sending side.  This also has the benefit for ham operations in that we can run it straight off a power source without the need for additional integrated circuits in the path.

The voltage range has been discussed in the past  so i wont go into to much depth other than to say its around 10.5-24v AT THE DEVICE this means it can be run from 12v battery (short cable run), 18v battery (longer runs) directly.  Can run from a car source, etc.

Glad to hear that I was not crazy. What you say is certainly good news. But, the down side is that active POE devices cannot be powered by Ubiquiti passive devices - example: an IP camera (active POE) coupled with a NanoStation M2 (not Nano Loco M2). In this given example, one would have to hunt up a passive POE camera to use with the NanoStation.

Thank you Sir

Just a note, that passthrough of data on  the 2nd ethernet port on the NanoStation is not currently supported (See BBHN->ticket:56) and is currently blocked by BBHN->ticket:61 needing to be implemented first.

Also we do not out of the box support passthrough of the POE Power to the 2nd port, there are guides online on how to do it, but due to the very limited amount of official information, plus some stories in the past of ports blowing (frying the passthrough transistor) (though it may have been a bad hardware batch) the passthrough power feature is not enabled or selectable at this time from the UI.
