At this location I have the following equipment:
01 x 6.5Ghz radio that needs -48V
01 x Rocket M5
02 x NanoBeamM5 400
01 x NanoBeam 16
01 x StarOS (very old 2.4Ghz AP with just couple very rural customers)
Before the Netonix switch, I used a Mikrotik Routerboard 2011. I had a 24V power supply and a 24V batter bank, but the -48V radio had no battery backup -- which was kind of important since it is the backhaul for this tower. Oh, and the electric service to this location is rather horribile. We probably have about 2 outages a month.
We installed a 48V 4A power supply + battery charger (
http://www.volt.ind.br/produtos-fontes-nobreak) and a 48V battery bank. We powered the 6.5Ghz radio directly from the power supply (inverting the + / -) and used a barrel connector to power the switch.
We powered the 3 NanoBeams just fine from the switch. The Rocket (which is an older XM model) would shut down the power supply any time we simply plugged it into the switch (no POE power). I'm not an electrician and don't fully understand the -48V bit, but I am assuming that something in the Rocket must be gounded differently than the NanoBeams. Anyway, we powered the Rocket with its original POE power supply and everthing worked out as we had planned.
We got rid of the Mikrotik at the tower. This location doesn't need layer 3 routing. Everything gets a VLAN back to the next tower and the Mikrotik there does all the routing.
