I wouldn't necessarily categorise passive PoE-out as 'useless' :-D When powered by 24v PSU, then sure - there is certainly some limitations on use of the PoE-out feature: as in it can only be used to power other devices that support 24v PoE Input. But throw away the 24v PSU and poer up your MT using 48v (for those devices that support >=48v supply) then you can power almost anything with that PoE-out port! Remember - 802.3af/at (etc) is all about the 'power-ing' device and not the 'power-ed' device - those active PoE mechanisms are intended to allow the power-ing device to manage power budget for connected devices and avoid being cooked by too many devices draining more current that the supply can manage. I've not yet come across a device intended to be powered by 802.3af/at that doesn't work when powered by passive 48v PoE - not saying they don't exist, just that I've not encountered one yet ; ) - so long as you have the right wiring scheme (i.e. 'type-A', 'type-B') then passive PoE should work fine for most. Cheers! Mike.

My W56P works just fine on 802.3af.
People just need to remember that Mikrotik/UBNT passive 24v PoE is mostly useless.

The Yealink W60B can absolutely be powered via PoE - I've got one sitting in front of me that's powered via PoE, as do many of our customers.

If it really doesn't then I'm a bit annoyed at Yealink for leading me on a wild goose chase.
