M4250 Switches Power Outages and UPSs

Hello,

I am working in a new theatre that was setup in some interesting ways. We are currently working our way back through the system and altering things to follow better practices. As it is a new building we are still dealing with power shutdowns as new equipment is installed/changed. Everytime there is an outage it feels like something new breaks. We have UPSs that our "critical" devices are (sometimes) attached to. This includes our network switches. But the batteries can only supply power for ~40 minutes at current load. Our UPSs have an expansion slot that we can add an SNMP network card into. Is it possible for our network switches to monitor for outages and power off nicely? Is there such a thing as shutting down the switches nicely? What is the best practice for shutting down a NetgearAV switch?

Another thing that causes outages for us is the fire alarm. We are required by the fire marshal to shutdown our whole system as soon as the fire alarm goes off. So currently everything loses power (except the UPSs which I think goes against the fire code... like I said... interesting setup) and I am trying to find better ways to manage shutting down the PA system but keeping critical equipment online long enough to shut down correctly before powering down entirely. We've had some false alarms from a poorly placed smoke detector in a catering kitchen and I would love to have a system that can shutdown according to code but do so nicely in case it is a false alarm.

I've had a bad experience with shutting down the M4250 switches. Early on when we opened we had a switch catch on fire after flipping the power switch to reboot it (following instructions from the installer) I want to prevent having this happen again.

I'm just interested in how people manage outages and turning equipment on and off.
