Yealink VoIP Phone Powered by Ubiquiti ER-X PoE
-
Anyone tried this combination? Does the power output on the one PoE port of the UBNT ER-X properly power the PoE input on a Yealink phone? We are specifically looking at the T42S.
-
I believe the ER-X is just passthrough, so if you don't have a PoE source, the ER-X can't power anything?

It could if you plug it into a power adapter, given that you don't have PoE in that case. You'd just use the PoE out if that were the case.

Either requires PoE source or power adapter. But it should still be able to power a device, with a power adapter, but without a PoE source to "pass through".

The ERX should work if the power injector that you’re passing through is one design for the phone and not the fixed voltage unifi

The ER-X models have warnings in the manual that you need a different power source than the included wall wart if you're going to provide PoE to a device. At that point, just use passthrough from a compatible phone adapter.
@JaredBusch already nailed it.
