Karl,
thanks again for your suggestion to use the Synology NAS as the UPS monitor!

It turns out that once I hooked up the RJ45/USB cable that came with the APC
ES700 to the USB connector on my Synology Diskstation 212j NAS I was able to
enable UPS monitoring and also the network UPS server on Synology.
The service itself was present out of the box! :)

So now the Synology NAS is checking the UPS state and it will shut down when
"battery is low".

I also enabled the network UPS server and configured it with the IP address of
my Ubuntu 18 server, so I assume that now the "only" thing I need to do is
figuring out how the Ubuntu server can use the UPS service on my NAS...

I installed package nut yesterday using apt on my Ubuntu server.
It entered a non-working state.

So now I "just" have to edit some config files, right?



With regard to another post in this thread:
I have set up my UPS system such that all of these items (and a few more) are on
UPS power:
- Incoming fiber interface to the Internet
- Main ASUS RT-AC86U router
- My two Netgear network switches
- Synology NAS
- Ubuntu Server (the target of my concerns)
- IP phone interface box

This seems to cover "everything" in case of a power outage so that my internal
network will continue operating with internal and Internet connection (assuming
the fiber provider's system is still on power).
