But the question is still valid, what if I decided I no longer want to use a UPS, there does not seem to be an option to remove it?
The action is triggered by the event being reported by the UPS. If you physically unplug it, then there is no device and therefore no event will be sent to the master.
If a shutdown is triggered by a switch going offline, then that is a serious bug. Are you talking about all QNAP systems here (as far as the NASes go and the monitoring)? I have multiple QNAP NAS running and configured against a single master and as of yet I have never seen an event trigger a shutdown other than a legit power interruption (and I've shutdown the master, unplugged network cables, unplugged the USB monitor, rebooted the switch/router that connects them all, etc). Of course there are always variables such as differences in the UPS brands, drivers etc but I would think and hope it would be seriously wrong if what you describe (a simple loss of connectivity) would trigger shutdowns. As you state, there are limited options in the UI but I would say it is a client issue. Although, you could look in the logs, if you still have them, to see why if the master or slave triggered the event, and hopefully why.
WAY back (30 years ago?) I know I had lots of different options (running a full UPS monitor system - I forget what it was called (powerAPC)?) where dozens of options existed to handle dozens of variables such as simple loss of connectivity.
If you are worried, disconnect all the clients (I object to the "slave" terminology) first, make your hardware changes, then add the clients back?
However, from what I've seen with my stuff, I would be 99.9% sure that it wouldn't be necessary, of course YMMV.
