mFi POE and US-48-500

Does the mFi use passive POE like most older Ubiquiti equipment?  I'm upgrading to the US-48-500 and wanted to make sure before I start changing the power on the ports the mFis will be on, or that the switch can't power them.  I may have missed it but didn't see it in the manual.

Yes, the mFi gear all uses passive 24V PoE. There are adapters than can convert them to standard 802.3af PoE devices (https://dl.ubnt.com/datasheets/instant/instant8023af.pdf), but out of the box, it's all passive 24V.

all you need to do it configure your ports to use passive 24v

Thanks everyone, I figured it was passive but thought I should double check, they're working great.

With any luck, by the time I'm having to replace these switches, something suitable for replacing the mFi will be available as well!
