We can't be the first to address this.
We are planning on running 3 sectorized antennas and 3 Rocket M5's at one site. Of course, we also want battery backup for it all, including the switch, right?
We'd prefer an 8 port, at least 4 of which are POE, VLAN capable and can run on 24 VDC. As the radios are Ubiquiti, of course our POE has to be 24 VDC maximum. A quick search only seems to turn up Netgear stuff, which is 48 VDC
What's out there?

The Ubiquiti Edgeswitches do run on 48V (or 115 VAC), but each port can be POE - either 24 or 48V POE. We use an 8-port one at a local site. I have it on 115 VAC, plus a 12V - 48V inverter for backup power in case of site failure. That one has been up 137 days.
