All 450i radios (except the 900SM) is 802.3at compliant. Then I guess
the question is, will the CTM port do sync-over-power in 3at mode? My
guess is no. You'll have to do the pin swapping that Cambium recommends
for the CMM4. Then tell your CTM that the port is 320/430 mode. But you
won't get gigabit obviously. Not like that matters on the 900 though.

I’m thinking more along the lines that my first test site for 450i 900
MHz will be at a tower where I already have a CTM-2 master + slave and
if it works out it will be replacing a 900 FSK sector that is
currently powered from the CTM-2.
So I was kind of hijacking your thread.

Would be nice if that did sync on all modes. But I already have a fair
amount of PF gear at this site. And I like it.

Hmmmm, what about a Last Mile Gear CTM-2?
It has 5 different modes. A is for 29.5V Cambium, B is for 56V
Cambium 320 and 430, and then there are 3 modes C/D/E for various
forms of 802.3at. Should I assume one of these will power a 450i
AP? What about timing, the documentation is not clear whether
these modes can do sync.

I assume that I will need a separate SyncInjector for the 450i
then as I have 450's in the mix as well. Would a Meanwell SD
120-48 PSU Work?

The SyncInjector can take up to ~57V (ignore the label). You
will need to power it with 48V to power the 450i.
There are problems with cable distance on SyncInjectors prior
to H1 (I beileve). Depending on your cable distance, you may
or may not see an issue from what I understand.

After looking at some of the earlier posts, I can't really
determine if I can use the 450i AP on a gigabit
syncinjector. It appears that it want a 48vdc power
supply. What is the best way to set this up? Or will it
actually accept the 29 vdc power supply on the SyncInjector?
