So what you'd need is a UPS on both your modem and router, then another one for the Apex. The apex would connect to the UPS via a little DC "wall wart" type adapter. If the power gets lost to the EB8, the apex will notice it and send an alert. If you wanted to power things via battery, you'd obviously need to connect those to the UPS, and probably get a larger UPS too...
You don't need a huge UPS for your modem and router though. They last quite a long time on a 500kva unit - of course bigger is better
