Re: Unusual question

There shouldn't be a motor in it. You might be hearing the sound of a power transformer somewhere in the garage. The BBU does have one that steps voltage down from 120v to where it needs to be.

Is the motor fairly loud in the BBU?

No motor in the BBU - just a power supply that converts 120 VAC to whatever voltage(s) the ONT requires. The power supply could be noisy and either hum or buzz but that is not particularly normal.

You'd have to walk around the garage and listen to figure out where the sound is coming from. If it appears to be the ONT/BBU you could try calling V* but whether they would do something about it is another matter.
