Just wondering what issues you've had with ZCP270s as we've had none in the past 4 years, although we do realize going forward that FCP270s are best (but were not originally due to limited number of FBMs).

We rigorously separate our units, but then we're a nuke. It's still a good idea. My best advice for mesh architecture is to make sure you can tolerate a complete failure. Avoid ZCPs like they're a bill collector.
