Installing Power
Plug the supplied 12V AC/DC Power Converter into the
connection on the rear of the chassis. Connect the power plug to a
standard 120 VAC outlet.
Using a UPS
The SFU ONT can typically use an un-interruptible power supply
UPS
( ) if desired. Power is supplied to the SFU ONT by a local power
source with battery backup that utilizes the AC power at the
customer premises. The UPS powers the SFU ONT and functions as a
BBU supplying continuous 12 VDC. Refer to the installation material
that is provided with the UPS when installing the BBU.
Connecting UPS
Connect the UPS to the 8-pin MOLEX connector labeled "UPS"
located on the rear of the SFU ONT chassis.
