Thanks, and there will be some situations where noise levels on grounding systems are enough different from the noise on the data that the surge suppressor will activate. But wow, that is a lot of noise. We have the lowest capacitive loading of the data pairs on the market. But again in a marginal situation, the suppressor could add enough NEXT or FEXT or loss or something to cause a problem.
I have probably sold in excess of 100K of these units. When there is a systemic design problem I hear about it right away from many parties. Generally we hear the odd one off now and then like this but nothing systemic. From: Brandon Yuchasz Sent: Tuesday, March 07, 2017 11:11 AM To: af@afmug.com Subject: Re: [AFMUG] UBNT issues Chuck. Interesting timing on this item. Last night I stated typing an update to my epmp, gps, microtik, packetflux issue thread from a few weeks ago. I didn’t sent it because I wanted to do just one or two more tests before I “put it in the wild”. Ill go ahead and send it right now but still plan to do some more troubleshooting when I get to the site later this week and will send out a final update after that is done. My network is also using MikroTik but is ePMP. Ill send it out.

We have over 100 APs, and countless backhauls running on these. I have every flavor of UBNT running on these surge suppressors, and have never had a single issue. We have AC gear, AirFibers, M-series, you name it.

Using the combination of the 3 we generate sever FCS errors on these links, which causes issues. If we bypass suppression, these links run clear and without issue. I have not heard of this before. We made some improvements that helped ePMP and 450 gear, but nothing like this. Many times odd issues like this are due to noise coming through the ground. I will attempt to replicate this once I know the exact gear to get. I wish the customer would just loan me the gear with the problem but I don’t know who the customer is.
