I think the "2"s here should be "1".

"powervalue is an integer representing the number of power supplies that
the UPS feeds *on this system*."

So if UPS_251 is connected to one power supply on the system running upsmon, and
UPS_252 is connected to another, then each powervalue is 1.

Or you could change this to 4, but that masks what is actually going on.

I tried all options:
1,2
and in MINSUPPLIES: 1,2,3,4
still didn't work.

UPS_251 and UPS_252 feeds all environment and it's not feed directly one
server, but many of them.

My mistake - I gave you the wrong advice before. For MINSUPPLIES, I'm used
to either a 1:1 UPS-to-server ratio, or 2:1 where the server can run with either
power supply unpowered.

I just tried this in upsmon.conf:

MONITOR dummy1 1 monuser password slave
MONITOR dummy2 1 monuser password slave
MINSUPPLIES 1

With only one dummy-ups set to "OB LB", upsmon kept polling. When both
were set to "OB LB", it tried to shut down the system.

That was with NUT 2.7.1 - I don't remember any bugs in this area, but it
would be in the changelog.

Right, and only the master is responsible for shutting down the UPS itself. Or
do you mean that not all of the servers are connected to both UPSes?
