I'm assuming that you have one UPS per server, and that server-1 is fed 
by UPS-1.

When server-1 shuts down, whichever server is in charge of UPS-1 should 
execute command

  upsdrvctl shutdown UPS-1

Does this happen?  Is this command called by a script or a systemd service 
unit?  Is there any trace of the action of that script/service unit in 
/var/log/messages or the systemd journal?
