Will any UPS work with Linux? (lemmy.world)

I'm down to the last few hours of discounts here. I need to get my NAS and my server onto a UPS months ago. Both are already set to come back on when power restores. We rarely have power outages and have solar panels (no house battery though), so a full outage is even rarer.

I understand that a UPS can send a shutdown signal when power is lost. Is this a universal standard or format for this? If so, what keywords should i use when searching for compatible products? My father told me to look for one with Ethernet ports. I just want to make sure everything is compatible. I go out of town occasionally and as well as preventing data loss, I also need everything to go down and come back up automatically so I don't have to call a friend, neighbor, or my spouse to go mess with stuff for me.

UPS brands considered (alternatives welcome): APC, Cyberpower

Systems protected, Synology DS 220+ & BeeLink MiniPC running Debian 12.

Also, for anyone who has helped me out previously in my self-hosted journey, thank you! Things are going great and I have a few useful docker images running various services and have set up grub btrfs snapshots to easily fix my screwups. This community has been incredibly helpful.

Not really, under an area blackout the fiberoptic transmitters will stop working, so you won't be able to reach other areas/nodes even if your equipment has UPS power.

But, in general, the idea of a UPS is to provide enough supply to allow for an orderly shutdown, preventing equipment damage or data loss. Its not meant for long term operations.

For infrastructure and other critical applications, the UPS is designed to give you enough time to go start the diesel generator, and continue the operations.

As a bonus, some UPS have filters to ensure that delicate electronics get a nice, clean power wave. This is usually the case in UPS for data centres.

Btw, how are you liking down under's "revolutionary" idea of Fibre + Copper? Is it as bad as it sounds?
