Here's where it gets over-complicated. I chose to run in a redundant configuration, with two switches at each location.

that doesn’t sound over-complicated to me; that’s how we do it on and off broadway, mostly.

Yeah, why put in redundant Dante without redundant power?

three reasons, for me.

first, because network failures are more likely than power failures. a carpenter dragging a piece of scenery over a cable bundle and slicing the network line feels pretty plausible. and a sudden failure (i.e. heat death) of an individual network switch isn’t likely, but it’s not out of the question.

second, because a power failure that takes out our networking is most likely to take out other show-critical things as well. obviously that’s not certain, but the vast majority of the power failures that i’ve experienced were upstream of any of my choices, and so there was very little or nothing that i could have done to prevent power loss across all or most of my system.

finally, i often put UPS in racks with network switches, which can protect against temporary power loss regardless of whether i have redundant sources of power. a physically isolated dante secondary network is the available analogue for this in the network data realm.
