Motorola?
At least Cambium is listening with making the Force180, Force200 and new
450 SMs that won't care about polarity.

No, 450 is regular 'ol Canopy. 450i is the same, but 48/56VDC.
BUT.... 56VDC mode on the CMM4 is wired for the 320 and 430 APs
which is why you need to reverse pins 5 and 7 for a 450i AP.
The 450i will take either polarity on pair. However, it has been
pointed out here and a few other places that you MUST have -4/5
+7/8 or the radio simply won't see the sync-over-power pulse.

The 450 Cambium is neither UBNT / Mikrotik nor legacy Canopy. A
3rd way. We use the dongles despite the price so there will be
some clue inside the power injector CMM4 If we get the urge to
swap some cables to test a port. Theoretically makes less smoke.

Ah, the old Betmax vs VHS routine. Swapping the pairs won't mess
up the
signal?
