Reminds me of the webserver UPS setup at a previous company.
The router (for the incoming T1) and the webserver were plugged in to the UPS.
UPS connected (via serial port) to webserver. Stuff running on webserver to poll whether UPS running from mains power or batteries and send panic emails if on batteries (for more than 60 seconds) and eventually shutdown the webserver cleanly if UPS power dropped below 25%.
Thing not plugged in to UPS: DMZ Network switch (that provided the connectivity between webserver and router).
