We have received a bunch of new 3.5 GHz 450i APs. 5 of these were integrated configurations, but one was connectorized. There is a noticeable gap in the middle of the top where the faceplate seals to the backing very similar to the pictures shared here, but it is not as dramatic. It is difficult to determine if that is merely a cosmetic anomaly or actually extends past the seal and will allow water into the case. Based on the conversation here, we are likely going to seal the entire seam around the unit the same way we do the connectors, vinyl tape covered with Monkey tape. Anyone see any issues with that?
We haven’t looked at the integrated ones yet, those are up next for inspection. Thanks, David Coudron [email protected]<mailto:[email protected]> | Mobile: 612-991-7474 Advantenon, Inc.

We've had our share of water intrusion issues with regular 450 APs. Cases where it was clearly a manufacturing/assembly issue, Cambium has made it right regardless of warranty status.

I have no reason to believe that this is a widespread problem. We use a ton of Cambium equipment and for the most part we are very happy with it's performance. I simply wanted to help the community by spreading awareness of a potential issue that is easy to spot before being deployed. Thank you Matt and Chuck at Cambium for helping out.

We got the same response. "Out of warranty".

We are located in Northwestern Oregon so we get plenty of rain. Upon investigation the metal case of the radio was not sealed all the way and water slowly seeped in. The unit was full to the top with water. By this time Cambium stated that it was out of warranty and we were burnt. I don't know how many of these units we have in the air are affected. This one is the only one that has died in such a fashion so far. Prior to this I wasn't really inspecting these for this issue and would have thought nothing of it. The seal must be farther inside, right? Today I was unpacking one new in box and noticed the very same issue, since now I look for this. We only use the connectorized version so I don't know if this issue is contained or morewidespread. Just wanted to throw out a heads up to everyone to keep an eye out for this since I got exactly nowhere with Cambium. I am not trying to pick on Cambium, just bring a recurring issue to light. This is a pic of the fried one that was in service for a year: This is a pic of the brand new one I took out of the box today next to one that looks fine: -- Matt Hopkins Network Administrator 503.687.1030<tel:%28503%29%20687-1030> [email protected]<mailto:[email protected]> onlinenw.com<http://onlinenw.com> <
