It would kinda be like buying a really expensive 24 port router and then just using 2 ports.....oh wait....that's what they did already.

Dual power supplies is a bit overkill. Although I remember my high school admin got a central router with dual power supply, but when you plugged both in at once (from the same source) they drew too much power on a reboot and flipped the fuse after every blackout.

shrug If you want it to actually work, all the time, go with dual hotpluggable PSUs on everything every time. And two separate UPSs.

If the cheapest router Cisco has with dual PSUs is a 39xx, well, I guess that's what you need.

Of course, there's an argument there that "99.999% uptime" is pretty pointless for a town library in the middle of nowhere, but that's a whole 'nother argument.
