AirRouter HP 5V POE?

AirRouter HP 5V POE?

I picked up a pair of used AirRouter HP's which do not work with 24V POE injectors. They came without injectors and when I attempted to use the 24V injectors that I have, the units began to blink which would indicate over voltage.  Anyone have any thoughts on these?  The underside of the units indicate 5V 2.0A.
​Are these older units?  Perhaps old enough to not be suitable for flashing?  
 
Any help would be appreciated.
 
Thanks,

Jim W8ERW

Can you get a board ID on this unit?

Can you power it up on 5 VDC and get the board ID?

1) The device must be running the AirOS
2) Telnet or Putty into the node (default user is ubnt; password ubnt; default ip 192.168.1.20)
3) Run "cat /etc/board.info"
4) Save the resultant file and post it in response to this post.

I will first need to get the proper injector or another power solution.  I assume both units are good, just not with the current 24V injectors.

Are you certain that thy are HP versions?  HP was the only version that had PoE.  The low power version used a 5V wall wart. (non-PoE)

Do they have an external antenna?

Yes, both are HP versions and

Yes, both are HP versions and they came to me without power adapters.  Looks like these are going to work.  Both powered up with a USB connection in the back and upon inspection, both are XM, 5.5.4 firmware.  Uboot reports Good Good and I have flashed the first one successfully with 3.16.1   I believe these are indeed units intended for 5V power via the USB connector.  And yes, there is the external antenna.  They are the same in appearance as the later HP versions.
 
Thanks everyone.  I think we are good to go.

AirRouter HP 5V POE?

The AirRouter "AR" model doesn't have an external antenna and will run with 5 Volts applied to the power port (coaxial dc connector) on the back of the unit or you can "reverse power" through the USB port.  Will take about .48 amps at 5 volts to run it.  The AirRouter HP model with the external antenna port runs off 10.5 - 24 volts POE through the WAN port.  I have found that although these units seem to "operate" with 5V power applied to the USB port, they don't seem to support any reliable connections through the Ethernet ports.

Both of these HP labeled

Both of these HP labeled units with antennas are marked 5V on the bottom.  Neither would operate with a 24V injector and blinked brightly when I attempted to do and in the same manner that the 24V model did when I had mistakenly connected a 48V injector.  They just blinked all the lights.  As was mentioned earlier, when I applied 5V to the USB connector, everything then worked as it should.  I have had them running for several hours without issue.  I was not aware of these earlier versions that were intended to operate on 5V from the USB connector.  The plus side is that they do work and might be quite handy somewhere when a 24V injector is not easily configured.  As portable units operating from a 5V USB supply, they would be easily operated from a standard 12V power arrangement and a 5V USB mobile charging cord of sufficient amperage.  I hope I can run into more of them.   Jim W8ERW

And look at the users guides and quick start guide at the bottom of the page.
The unit you describe is supposed to be powered with a wall wart poe ejector.
If you can't find the original Ubiquiti 5V/2A POE then you can use a poe like this one and feed it with 5 volts.

Mesh Chat on this 5V AirRouter HP

After some effort to find a suitable power arrangement I have a pair of AirRouters operating as they should with a 5V source via the POE port.  However, now I find that MeshChat appears to load but does not setup as a service and is not available.  Anyone have any thoughts on this?  Again these are apparantly earlier versions of the hardware that do indeed operate at 5V rather than the 24V newer units.  Yes, they have external antennas and otherwise appear to operate the same.  They do not appear to appreciate MeshChat however.  Thanks,  Jim W8ERW

I doubt the hardware is the signficant cause here.

Unfortunately  MeshChat is still very early in its development and I"m not aware of any recent development on it.  Flaws have been noted across various forums. 

That said the software developer would be the best individual to contact with these concerns so they can create new versions that resolve any flaws.  If it ever becomes open source licensed someone could also take it up and work on it as well for the community, but until that time only the author who holds copyright to it can really resolve these sort of concerns.

AIRROUTER AR are "LABELED" as HP

I may not have mentioned this before, I've noticed that AirRouter AR Models are actually labeled as "AirRouter HP" on the bottom.  Easy way to tell if it is an "AR" is there is no external antenna jack and it is labeled as 5V with a Coaxial DC connector.  You can also reverse feed the USB port with 5 Volt power @ around .5A.
Everything else works the same - put UBNT 5.5.11 XM on them and you are good to go to load AREDN Firmware. I have seen a few units with UBNT 5.5.8 that won't accept UBNT 5.5.11, but they will work fine with AREDN as well.  Recommend staying with 3.16.1.1 Firmware until the production release if you plan to use them as Tunnel Clients or Servers.

AirRouter AR vs HP

Those of you with more Ubiquity experience may have additional information on this.  The two Ubiquity AirRouters in question here are indeed labeled as HP.  From appearance they are the same as current hardware.  There is no coaxial power input, but they are in fact labeled as 5V.  They also have external antennas and can be powered via reverse feeding the USB port as well as POE.  I have verified both successfully.  They appear also to have the same memory configuration as current units.  They have both been successfully flashed to 3.16.1.1 from UBNT 5.5.4.  A couple of issues have surfaced.  One is the inability to load MeshChat.  It does appear to load, but no service is then listed.  I manually input the service which did not result in MeshChat working.  The other issue is that on one other node on the mesh I have been working with reports the node twice in the Mesh Status screen.  Interestingly, one does show MeshChat while the other does not.  The second of these units only shows up once and with MeshChat.  I attempted to resolve the duplicate listing by allowing the entire MESH to power down for over an hour with no change in the duplication  As I continue my quest to figure this all out, I will post any additional findings.  Thanks to all of you who have offered suggestions and information on these two alien devices.  Jim W8ERW

weird, as HP models require more than 5v usually

these seem to be unique HP models.

For the non-weird Air-Router HP models, I have instructions to use a 12vdc wall-wart to power them in case you don't have a POE... or 120vac for the POE:

while on this subject, the popular Grandstream 1600 series VoIP phones run off 5vdc.  Here's a cable that takes 5v from USB:



You will see all types of these being sold, I seriously recommend using the one made by Tripp-Lite:

AirRouter HP 5V POE?

Hi Tim,
 
Indeed, the Tripp adapter works very well and I found these two strange HP units to work well on a 5V USB source as well as trough the POE connection using a passive injector with a 5V wall wart.  Your 12V method would be a handy solution when there is no available AC and especially in portable situations.  I have yet to try that, but likely will before Field Day this year.
 
Thanks for the input,

Jim
