said by Thinkdiff:Yes, you are right. I opened the top box and it has a black three prong plugged into a white three prong that goes up into the verizon surge protector that attaches to the battety. I should plug my extension cord fromy power supply into the black cable correct? I have a generator that first plugs into a surge protector the extention cables coming out of that.
I have the same ONT. There should be a regular 3-prong power cord coming out of the top (if i remember correctly) going into a Verizon surge protector/grounding box and then into an outlet (might not have this in some areas).
Unless they wired the ONT directly into the panel, as it is pretty close.
