Re: 48VDC Power Adapter for EdgeMax Router POE?

Will be going with the EdgeRouter PoE (ERpoe-5).  I need to run two UAP-Pro units via PoE.  Will I need a 48VDC power adapter as well and does Ubiquiti have an official one yet?

As mentioned above we are working on this but do not have anything official yet. We will provide an update when there is new information.

Re: 48VDC Power Adapter for EdgeMax Router POE?

Thanks, but will the EdgeMax Router PoE require a 48VDC power supply to properly power to UAP-Pro. units via PoE?

Re: 48VDC Power Adapter for EdgeMax Router POE?

Yeah UAP Pro needs 48V, and as mentioned above and in documentation, 48V power supply is required for the ER PoE to output 48V.

Re: 48VDC Power Adapter for EdgeMax Router POE?

So as long as I get a 48V power supply for the EdgeMax PoE, it will be able to power two UAP- Pro. units?

Re: 48VDC Power Adapter for EdgeMax Router POE?

Yeah something similar to the ones mentioned earlier in this thread should work.

Re: 48VDC Power Adapter for EdgeMax Router POE?

I've been using a 60w 48V 1.25a power supply since the ER5 was released. It's reliably powered a single UAP-AC.

I recently add a 6w max 802.11af Netgear GS108T-200NAS switch powered by the ER5.

My question is can I add one more switch (2 total) and power it off the ER5?

The ERPoe 5's warranty isn't voided by using these 3rd party power adapters?

See Post Number 10.  This question has been answered.  :-)

Re: 48VDC Power Adapter for EdgeMax Router POE?

Wow, so they don't make an official Ubiquiti 48v DC power supply for the ERPoe 5 and they don't have a list of recommended ones.  So if we need one and the one we get causes damage to our ERPoe 5, we're screwed...

So what happens if I connect a 30 volt power supply? :manhappy:

Re: 48VDC Power Adapter for EdgeMax Router POE?

Yes you are right that currently we don't have an official 48V power supply yet, and as you know this is pretty much what's been discussed in the previous two pages of this thread. :icon_smile:  And as mentioned we have been actively working on a solution for this but it takes time as it involves sourcing from different vendors, compliance testing (EMI, etc.), cost, etc. We will provide an update as soon as we have more specific information. Thanks for your feedback.

Re: 48VDC Power Adapter for EdgeMax Router POE?

Guys, is this an appropriate 48v power supply?

48vdc/1.25a Power Supply

Anyone find anything better/cheaper?

Re: 48VDC Power Adapter for EdgeMax Router POE?

I'm using the exact the same Meanwell adapter since the ER5-POE was released.  I'm powering one UAP-AC and two Netgear GS108T-200NAS over POE.

Re: 48VDC Power Adapter for EdgeMax Router POE?

My two cents:

this is silly

just had to spend $50 on two power supplies to use EdgeMax POE router with UAP-ACs - please include the correct power supply in the box!

Re: 48VDC Power Adapter for EdgeMax Router POE?

Yes understand your point of course. As mentioned above this is something we are working on and it will still take some time as it involves many different issues. Thanks for your patience.

Re: 48VDC Power Adapter for EdgeMax Router POE?

As 60 watts of 48v POE isn't really enough to drive all the ports with 48v gear, they will likely be walking a tightrope here. One 48v radio such as a Rocket Ti and a couple of UniFi AC and you've maxxed the specs on all the 48v supplies with the type of power connector that's used on the small Edgerouters.

I haven't seen any greater than 60 watt 48v supplies with that connector type.

I bought a 48v supply from Streakwave to give it a try on my workbench. I am going to see how well it does with two UniFI AC and then three UniFI AC. I think that three may push it over the edge but it's hard to tell exactly the draw of a UniFI AC in the real world, anybody done any testing like this on thier own? Has UBNT released a guide detailing what's supported and what's not supported in the 48v configuration?

The Edgerouter POE was a nicely conceived product but I fear with more POE ports than POE power it's set itself up for failure. I like the idea of a 3-5 port router in thier small package size, so I've so far been running one of those and a Toughswitch 8 port as a combo so that I can drive a variety of PoE devices at 24 and 48v and not need to worry about driving it into an edge condition inadvertantly.

The power supply from Streakwave was about $19. The only downside was that it is not a grounded cord, so if thats important to you there have been a few other supply optiojns posted by others way earlier in this thread that spec'ed grounded versions of a properly connectorized 60w 48v supply.

Re: 48VDC Power Adapter for EdgeMax Router POE?

@wayneco,

I believe there is another thread on testing the PoE with multi-UAP and other devices. -> https://community.ubnt.com/t5/EdgeMAX/Field-tested-ER-POE-S-on-my-live-network/m-p/538592#M13175


The Meanwell 60W 48V 1.25A PS I have gotten (from where I resides in) comes in a different 3 pin grounded specs. :manwink:

It's been 6 months since UBNT has said that they're evaluating compatible 48v power supplies and there's still no first party option so I've been looking for alternatives.

It looks like Linksys/Cisco shipped a 120w 48vdc 2.5A power supply with the 5.5x2.1mm plug as Cisco PN GPSESU-482P51-IE7FG.  Here's a picture for reference.  Linksys also has this as PN 0432-00VE000.  The OEM PN looks like FSP120-AFB, but there appear to be a few different models with this number.

There's been some talk in the thread here about 60w power supplies and having some difficulty finding 120w options.  Is there any reason why I shouldn't use a 120w supply?  Will the EdgeMax Router PoE handle 120w OK?

Yes, it will handle 120 watts just fine
