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?
