WARNING!

Ensure that the 611 GPON ONT does not come in contact with 
water or other liquids.

Wall Mounting

Refer to 

Figure 3

 when installing the 611 GPON ONT on a wall.

1. Decide on a location for the 611 GPON ONT. Mount below eye-level 

so the LEDs are visible.

     NOTE

Supplied hardware is intended for drywall mounting only. For 
mounting on surfaces other than drywall, obtain the appropriate 
mounting hardware and follow the provided instructions.

2. Use the keyholes on the rear of the 611 GPON ONT as a template 

and mark the wall accordingly. The keyhole spacing for a vertical 
mount is 1.97 inches (5 cm).

3. Drill holes using a 1/4” drill bit into the marks on the wall.
4. Use a hammer to lightly tap the included wall anchors into the drilled 

holes until anchor is flush with the wall.

5. Install two included screws into the anchor heads. Leave 

approximately 1/4 inch (6 mm) protruding from the mounting 
surface.

6. Slide the 611 GPON 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.

Step 2: Connect Ethernet

Refer to 

Figure 2 

on page 1 and insert a Category 5E (or better) RJ-45 

cable into the port labeled 

GE

 until there is an audible “click”.

Step 3: Connect Fiber

Power

Power is provided by a 12 V DC Power Adapter that is included with the 
611 GPON ONT. The power adapter operates from a power source of 100 
to 240 V AC, 50 - 60 Hz. For the United States and Canada applications, 
an NRTL Listed Limited Power Source (LPS) is needed. For deployment 
in international 

applications, an LPS specifically approved for that country, as indicated by 
a CE Mark, is needed.
