Power-Outage

For some reason, it’s been a bit hard to find information on how to setup my particular fiber ONT so that it can survive a power outage with a PoE setup.

While of course, one could power a whole house with solar and batteries, I wanted to find a way to keep my fiber ONT and router powered during a power outage without having to invest in a full home battery system.

Costco recently had on sale a small EcoFlow RIVER 3 Plus Portable Power Station, which I installed into my home network setup with the power station being next to my router.

It’s been wonderful as an UPS!

My setup is a bit peculiar as my Frontier FOX222 ONT is a bit far from the power station, but the power station is next to the router and there is an Ethernet cable running from the ONT to the router. The RIVER 3 is also next to the router.

The only way to provide power to the ONT without also having to plumb AC backed by the power station: A PoE injector on the Ethernet cable between the ONT and the router and a splitter at the ONT end to convert the PoE to 16V DC power for the ONT.
