ADI Communication Failure

I have encountered alot of PMP450 SM that fail to operate, displaying the ADI Communication failure. What is the root cause of this problem and what could be done to prevent it?

Hi,

It is related to Hardware issue. In order to resolve this issue, we need to repalce the unit. 

Below is the field service bulletin on this issue.

This issues was really bad in the first several batches of SMs  we recieved, and then it went away, now I have noticed its starting to bring its ugly head back out.. All you can do is contact Cambium support and RMA them. It's a painful process, but a nesscessity!
