We are primarilly Canopy for CPE gear. What would really be nice is a RB750 or similiar with a POE output that could power up a Canopy SM. Nicer yet a jumper inside to swap polarity so it could power either a Canopy or a Ubiquiti SM. We could delete the Canopy power supplies from our installs and use that expense towards the RB750 with POE output. It would use less outlets at a custommer location and each user would then have a high quality managed wifi router. The big thing is there would be less devices at the custommer location to have plugged in wrong.
Simply make a sort of "crossover’ cable with blue=4/5 and brown=7/8 pairs swapped (the usual crossover cable to connect 2 NICs without a switch swaps the orange=1/2 and green=3/6 pairs), that will reverse the polarity without modifications to the RB750UP. Be careful to not damage radios by wrong polarity, hopefully the RB750UP short circuit protection is fast enough.
