Installing Power
Plug the supplied 12V AC/DC Power Converter into the
PWR
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. The illustration below
represents the MOLEX connector on the rear of the ONT.
The UPS Power/Alarm Connections Table at the top on the next
column defines each pin on the connector.
NOTE
ADTRAN offers a UPS Cable assembly (P/N 1287402G1) for this
connector.

ON/OFF Button
An On/Off button is located on the far-left side of the rear of the SFU
ONT. User functionality is limited to this button.
NOTE
If a BBU is being used and is disconnected, the SFU ONT is not
protected from power outages, and will send a “Battery Missing”
alarm to the OLT.
