Re: Do I really need the BBU?

(27,375 Views)

If you have a whole-house generator (and the power cord that goes to the [battery charging circuit and ONT] is part of what that generator covers), you absolutely, positively do not need any battery in the BBU. I have no battery in my BBU at all and haven't had one in a year or so. Instead, I plugged the ONT's BBU into a UPS. It's weathered several 10 second to 20 minute power outages with no loss of Internet. This is even better than the BBU approach is that only backs up the land line telephone service. It seems it backs up the internet and TV for a short while (on the order of 2-3 minutes). After that, only the telephone continues to work.

My setup: 75/75 Mbps; Linux router (2x 1Gbps ports) + iptables; Netgear Orbi x 2]
