Awesome. 5 days after turn-up and this happened. Granted, it's a pretty
long path and we knew we'd see fading, but that's what ACM is for. I've
heard nothing but good things about SAF and the Lumina platform, so this
is pretty hard to swallow. I really like these radios and their
features, too. Everything else at the sites is +48VDC, so we went with
these because they're polarity agnostic. So I guess this will be the one
and only, and last SAF link we deploy. This is a major deal-breaker for me.

I've had the same problem with my 6GHz Lumina, several times.
The answer from support was "reboot it". No indication if this would
happen again, what I could do to fix it, or what might have caused it.
At this point I have a 1+1 Lumina plus a 5GHz backup link for when the
SAF drops.
I haven't had a problem with it for a while, however now that I've
said something ...

So I have a 6GHz Lumina configured for 56MHz/256QAM ACM weak FEC. We
are coordinated for variable power and it is active. It's a ~30 mile
path on horns. Apparently the link took some fade yesterday morning.
One side was stuck on 32QAM strong FEC. I figured meh, it'll clear.
Well I just looked again and it didn't. I had to reboot (power-cycle
was easier) both ends to get it unstuck. Came right back up at 256QAM
both directions. Anyone else seen this before? Is ACM on these just
stupid?
SAF, WTF, I should not have to reboot a $6k pair of radios! And yes,
these were shipped with the latest firmware.
