If the UPS is not equipted with a network management card, then you can only
connect the UPS to one server.
This does not mean that you can manage only one server! The UPS software let
you run custom scripts on (shutdown) events.
Create ssh key-pair on second server, and create a rs(s)h script to logon
with the just created ssh keys to the second server where it runs a
(shutdown) script. This can also be done for the third fourth and so on. You
of course run different scripts on different events....
