Power Connector
The power feed is +12 VDC from the included AC/DC adapter.
The adapter plugs into the POWER connector. The total power
consumption is less than 10 watts.
RJ-45 LAN Interface
The 422G CPE supports data service through one 10/100/
1000BASE-T Ethernet interface via an RJ-45 style connector.
RJ-11 Gfast Interface
The RJ-11 Gfast interface is used to connect the 422G CPE to a
wall phone jack. This provides Gfast capabilities using the existing
phone lines.

Step 2: Connect the Ethernet Cable
The 422G CPE supports a gigabit Ethernet (10/100/1000BASE-T)
connection via an RJ-45 style connector.
Insert a Cat 6 rated cable from your device into the RJ-45 LAN
port on the back of the 422G CPE (see Figure 1 on page 1).
Step 3: Connect the Gfast RJ-11
fCAUTION!
For RJ-11 connections, to reduce the risk of fire, use only 26 AWG
or larger (e.g., 24 AWG) UL Listed or CSA Certified 
Telecommunication Line Cord.
Insert the RJ-11 connector into the RJ-11 G.FAST port on the back
of the 422G CPE.
Step 4: Connect 12 VDC Power
gNOTE
Only power the 422G CPE with the AC/DC adapter supplied with
the product.
Connect power as follows:
1. Plug the supplied 12 V AC/DC adapter into the POWER 
connection on the back of the 422G CPE.
2. Connect the power plug to a standard AC outlet.

Desktop Installation
Place the 422G CPE in a location that does not receive direct
sunlight and is not next to any thermal obstructions or sources of
moisture.
Wall Mount Installation
To wall mount the 422G CPE, complete the following steps:
1. Select a location for the 422G CPE.
gNOTE
Do not mount the 422G CPE higher than 9.8 ft (3 m) from the
floor.
2. Use the key holes on the bottom of the 422G CPE as a
template and install two #6 drywall anchors (see Figure 2).
Figure 2. Wall Mount Keyholes
3. Install two 0.629 in (16 mm) #6 pan head screws into the
drywall anchors. Leave approximately 1/4 in (6 mm)
protruding from the mounting surface.
4. Slide the 422G CPE over the pan head screws (see
Figure 3) and exert a small amount of downward pressure to
ensure that the top of the slots are resting on the shafts of
the pan head screws.
