5. Install two screws (included) into the anchor heads. Leave
approximately 1/4 inch (6 mm) protruding from the mounting
surface.
6. Slide the 621i ONT over the screws and exert a small
amount of downward pressure to ensure that the top of the
slots are resting on the shafts of the screws.

NOTE
Alternately, wall anchors are not needed if mounting directly to
wall studs.

CAUTION!
To prevent breaking the fiber, do not exceed the fiber bend radius
of 3.5 in (8.9 cm).

CAUTION!
LASER RADIATION - 1310 nm to 1600 nm
Do not view directly with optical instruments.
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
Fiber is installed in an SC/APC connector (
the rear of the 621i ONT (see
steps to install fiber.
1. Remove the Dust Cover from the SC/APC Connector.
2. Clean the end of the Incoming Fiber Connector.
3. Before installing the fiber, use an optical power meter to
measure the dB power. The level should not exceed –8 dB.
Use an appropriate bi-directional optical attenuator if the
power levels are at or above –8 dB. A level between –12 and
–18 dBm is acceptable.
4. Connect the Incoming Fiber Connector.
Step 4: Connect Power
To connect power to the 621i ONT, complete the following steps:
1. Plug the supplied 12 V AC/DC Power Adapter into the
connection on the rear of the 621i ONT.
2. Connect the Power Adapter to a standard 100 - 240 V AC
outlet.
3. Verify power is on by checking the power LED on the 621i
ONT. The LED should be green, indicating local power is on.

CAUTION!
For United States and Canadian applications, the DC Power
Adapter must be an NRTL Listed LPS power supply. For
International applications, the DC Power Adapter must be an LPS

When the 621i ONT first powers up it performs self-tests. Once
the power up self-tests are complete, the status LEDs will reflect
