I believe the 450m is like the 450i. Doesn't matter what polarity each
pair is. Just two pairs negative and two pairs positive. However, as
Forrest pointed out recently, you MUST have -4/5 & +7/8 for
sync-over-power aka "Canopy Sync" to work. And I believe Cambium said
the 450m uses "Cambium Sync" (whatever that is, I still don't know), but
Sean said the 450m's he has in the air are receiving sync over power
just fine.

Thanks, George. I thought that might be the case, but wasn't sure..
What would be the polarity on the 1/2 and 3/6 pairs?
cheers

It needs power on all four pairs. The default is -4/5 +7/8. So you
need to put power on 1/2 and 3/6, too. Open the case. There's a
diagram printed on the left side of the board. And yes, there are
spare jumpers already there on each port.

Howdy folks (and Forrest, in particular!)
Can the gigabit PowerInjector+sync gadget be used to power the 450m?
We tried it once with the default Canopy configuration and the 50V
power supply, but it acted sketchy and wouldn't survive a reboot..
The sticker on the powerinjector mentions a manual on the website,
but I've not been able to find it.
cheers,
