Model: EAP225-Outdoor  
Hardware Version:
Firmware Version:

When installing the access points at a location, there needs to be a power receptacle nearby to provide power to the AP..

I have an application where power is not easily accessible at each point where I want to place an AP. This is a marina where the logical place to mount an AP is on the pilings that support the docks. These present several problems. One, there is no power nearby and Two, if there was nearby power, there is the problem of the dock rising and falling with the tide making wirinng difficult and subject to damage. It would be much easier to have the AP mounted to the piling supplied with power right at the piling.

Has anyone attempted to provide power via solar power? The AP does not need much power and I would think that this could be done in a manner similar to the way highway signs are powered.

If I used a setup like that, I would need to incorporate an RJ-45 jack with the power delivered to the appropriate pins. I also need to know which pins to use!

Surely someone out there has had this idea and would be willing to share the details.

@Byteguy, it's 24 volts on both + pins, but your basic idea is correct: the current is splitted up between the two wires.

@Byteguy 

 

In your network requirement, we recommend you to use the solar power for the adapter of the EAP225-Outdoor. As long as the output power is similar to the standard, it will be ok to power for the adapter.

@Byteguy If I am understanding your reply, you recommend I use solar converted to AC and then plug the adapter into it. If I knew the voltage required, I can bypass the adapter and power the EAP directly. I see that is uses 10.5 watts, but how many volts?

We can see this information from the spec of the EAP225-Outdoor.

@forrest True, but there is no reference to voltage.  Sort of important, isn't it?

@Byteguy,

 

the input voltage of almost all modern switching power supplies is 100 to 240 volts AC. Input current of the EAP225-Outdoor adapter is 0.4A, AC frequency is 50/60 Hz, output voltage is 24 volts DC, max. output current is 0.5A.

 

You can find those specs on the label of the EAP225-Outdoor PoE adapter and in case you want power the EAP directly w/o transforming to and from AC, you can see the voltage in @forrest's post of the specs:

@R1D2 Got it.Musta been looking in the wrong place. Even refers to the pins.

Commercial solar outfits seem prohibitiely expensive. Probably because they are converting to AC. This is why I was wondering if something going directly from the solar panel, through a battery, might work. Not my area of expertise.

Just a thought--pins 4 & 5 and 7 & 8 are being used. Wondering if each combo carries 24 volts or is that split between pairs (12 v each). My client will be ordering 3 more EAPs so I guess I'll plug one in and measure the voltage.
