You are correct, the POE version adds the transformer.

Uh oh. I figured it out. It was as I suspected. The SS is clamping due to the
sync pulse. Maybe the change that Forrest made with the Rev i0
SyncInjectors/PowerInjector+Sync because of the 450i's finicky handling of the
pulse over long runs? I have no idea. So much for GigE + sync over power I
guess. I don't have any Rev i0 Gigabit SyncInjectors to test with, but I assume
I'd get the same result.
I set the AP back to negotiate GigE. Turned off the sync on the injector port
feeding that radio. Rebooted the AP. Link stays up at gigabit with no problems.
Then I turned the sync pulse back on and the link dropped almost instantly.

The GigE-APC's I have at this site are definitely HV's. That's all I have ever
ordered. They are all marked HV in sharpie on the handle. I'm feeding that
cluster with regulated 24VDC from a RSD150C-24.

Uh.. hmm. I have a 5.7 450 sector running at a tower without any customers on
it yet. It's powered and timed from a new GigE PowerInjector+Sync. GigE-APC-HV
at the bottom. No SS on top. ~225 feet of Shireen 1042 cable.
I just logged into it and set it to Auto 1000F/100F/etc. and rebooted. Does
the same shit.

I also just set it back to Auto 100F (disabling gigabit negotiation) and it

So, looks like the boot loader brings it up at 1Gbps, then the config makes
it fall back to 100Mbps.
This is also the first time that I tried messing with GigE on the 450 since
updating from 13.2.1 to 14.1.2.
This is a regular old RB1100. I have an Exalt ExtendAir G2-11 and an AF24
each running on a GigE-POE-APC and gigabit works fine. Chuck would have to say
for sure, but I don't think there's much electrical difference between the
GigE-APC-HV and the GigE-POE-APC. Besides maybe the gas-tube backup suppression
and GigE transformer.
Me thinks this has more to do with Cambium.

I upgraded two CRS125-24G-1S-RM's to 6.36.3 (current branch). Both brand
new out of the boxes. Upgraded boot firmware to 3.33 on both. Reset both to
defaults. Ether24 to ether24 linked up at 1Gbps FDX. Ran MT bandwidth tests
between them. No issues.
Then I put a GigE-APC-HV in between with a 50' patch cable on one side and
a 10' on the other side. Tried with and without the ground attached. Ran more
bandwidth tests. No link drops. No errors.
So... I have no idea why you're having problems. The ones I have are
definitely HV Rev A1's.

Do you have a GigEAPC-HV? My setup was CRS125 -<~50 foot
UTP>-<GigEAPC-HV>-<20 foot UTP>- CRS125
