This is actually a follow-up to an earlier post by me: Protecting an ONT with a UPS - Good Idea?
In that post I explained that I wanted to protect my ONT with a UPS. I described my situation as follows:
I have internet-only service with Verizon. My ONT (which is in my basement) is attached to a battery backup from Verizon, which in turn is plugged into the wall socket. Verizon's battery backup isn't needed for internet-only service; it was probably installed so that if I ever wanted to add Voice service, Verizon wouldn't have to send a technician to my home.
I was correctly advised to remove Verizon's battery backup, so that my ONT will plug directly into my UPS, and the UPS will plug into the wall.
But there's a problem.
The power cable that connects my ONT to Verizon's battery backup does not terminate in a three-prong plug. Rather, it looks more like a co-axial cable. In fact, there is no three-prong outlet in the ONT. So if I were to remove Verizon's battery backup, I don't see how I could plug the ONT into the UPS. (There's no co-axial connector on the UPS.)
It seems like I'm stuck with Verizon's battery backup - I'm going to have to plug that into my UPS, and my UPS into the wall socket. So I have three questions:
1- Is there a better solution? (Perhaps to replace the power cable coming out of the ONT with the same type only with a three-prong plug at one end, if such a thing even exists.)
2- If I have to add the UPS after Verizon's battery backup, will that arrangement work properly?
3- Is such an arrangement safe? I don't know if there are actual batteries in Verizon's battery backup. I presume 'yes' but I would have to take it apart to find out. I guess I'm afraid of the batteries overheating or bursting.
Thanks again for your help.
