ONT Power Supply Unit (OPSU):
Finding your electricity source
Your ONT requires electricity to operate all
Verizon services provided on the FiOS network.
The OPSU supplies power by connecting your
ONT directly to an electrical outlet in your
home or garage.
The OPSU contains a single indicator light that
tells you if electrical power is present. If the
indicator light is dark, electricity is not flowing from the outlet to
the ONT. In normal operation, the light should be green.
The ONT requires very little power to operate. In fact, the amount
of power needed is as little as what it would take to operate a
couple of night-lights.
To ensure connectivity to the Verizon FiOS network, please make sure your ONT
Power Supply Unit is plugged in at all times
.
