3rd Party power injectors with AP1562I

Hi,

I have a few of AP1562i. We decided to deploy a couple using a 3rd Party power injector.

Brand = Ubiquiti

Model = gp-c500-120g (POE-50-60W)

Unfortunately, the AP doesn't seem to be able to turn on. However, the injector works with AP1850 series.

We tried connecting the AP1562i to a 60W cisco switch and it does function.

Is this a poe compatibility issue? Can the 1562i support other 3rd party poe injectors? Can anyone recommend any non-cisco POE injector that will work with this device?

I am not going to recommend any 3rd party injectors for the 1562i/e/d because I know, from experience, they are very "picky".

Like Leo says - at your own risk *but* at a minimum it MUST be IEEE 802.3at (POE+) standard compliant and must support LLDP or CDP power negotiation. Looking at https://www.ui.com/accessories/poe-adapters/ they don't even mention 802.3at or POE+ either on that page or on the pdf datasheet, and they describe these as "PoE Adapters power Ubiquiti® products that support passive PoE" so I think you were very optimistic to even expect that to work at all.

If you want to experiment with 3rd party injectors then start with a product which is 802.3at compliant which means it must support LLDP at least (more bugs) but CDP is better for Cisco kit - which is why Cisco injectors work better.
