Start with telling us what UPS you have. APC makes their software
source available, though I am told it does not use the smart mode.
The SuSE 7.1 CDs have argoups, smartups, and upsilon. I could not get
smartups to work with my APC Back-UPS 650. It detected power failure
but never detected low battery and so never did the shutdown. I use
the APC SSD package.
The communication between slaves and masters is over the LAN.

Connect the UPS to one Linux, the master. It tells the slaves to shutdown, wait a period for comfirmation, shuts itself down and turns off the UPS. Details depend on the UPS brand and model and which UPS software you are using.
Wow... Great.
But, *how* tells the slaves to shutdown? UPS software on master, or must I write some script? (I don't use any UPS monitoring software by now).

solution
