I think that most of these items are needed for the distributed system to work:
- Router because otherwise the internal network will be unavailable
- Fiber box, without which there is no Internet
- Network switches for the same reason
- Synology NAS manages the UPS and has important file storage
- Ubuntu Server, the reason I started this in the first place

I have not hooked up printers or laptops (they have internal batteries after
all) etc. And I don't think the fiber interface box pulls that many watts of
power either. And my mission was to make sure I had Internet available also in a
power outage.

So I think it should be OK now.

Concerning configuration I have found two how-tos that are informative:

https://diktiosolutions.eu/en/synology/synology-ups-nut-en/  

Then after logging on with SSH to my NAS I could see what the default "user" for
UPS is set to and use that in the Ubuntu config. Did not need to change much.

Then I intended to check if the UPS connection on Ubuntu worked properly when my
ISP suddenly dropped the fiber! Grrrr....

So now I have had to set my phone as a hotspot and connect my laptop to that
just in order to get onto the Internet and report the fiber outage to my
provider...
