I got myself an APC ES 700 UPS after the hickup when we had the power outage
described in thread "Power outage now my server asks for fck, what to do?"

In the process of connecting up my stuff (fiber box, ASUS router, network
switches, NAS, Ubuntu server) I am pretty much done now.
I looked at the APC homepage but it redirects to "Schneider Electric" and sets
the page language to Swedish so English is not available. Furthermore it states
that the product is expired....

The download available for software only contains a Windows installer, nothing
for Linux... :(

Since people here have been talking about hooking up the Ubuntu server to the
UPS such that it will shut down sensibly when the battery power nears its end I
wonder how exactly this is done?

There are three RJ45 sockets on the side of the UPS and one is apparently really
a USB connection to be hooked up using a converter cable supplied with the UPS.
That cable has an RJ45 in one end (like a network cable) and a USB-A on the
other.
But how is it used on Ubuntu?

I have not seen any "upsmon" program on my Ubuntu 18.04 server in any case (if
that is the correct name)...

Or is it nut-client? Strange name in that case...
