E31U2V1
DOCSIS 3.1 eMTA

!
Device Grounding: Install the eMTA to include grounding the
coaxial cable to the earth as close as practical to the building
entrance per ANSI/NFPA 70 and the National Electrical Code
(NEC, in particular, Section 820.93, Grounding of the Outer
Conductive Shield of a Coaxial Cable). The device is designed for
IT power systems with phase-to-phase voltage at 120V.
This unit requires a 100-240V, 50-60Hz power adapter. The power
adapter must be keyed for proper polarization, and must be fully
inserted to contact the back of the power connector port to
ensure snug connection. Use only the supplied power adapter.
Disconnecting the Device: If the eMTA becomes damaged or
encounters some other abnormality, disconnect the power adapter
from the AC wall outlet immediately.
Temperature and Altitude: Install the device in a location not to
exceed the maximum operating temperature of 104˚F (40˚C).
Maximum operating altitude is 5000 m (16,404 ft.).

•INSTALLING THE MODEM
1. Connect the coaxial cable (not supplied) to the Cable
connector on the rear panel of the eMTA and connect the other
end to the cable wall outlet. Do not bend or over tighten the
cables, as this may strain the connector and cause damage. To
connect an eMTA and a television to the same wall outlet, you
must use a cable line splitter (not included).
2. Connect the Ethernet cable (supplied) to the Ethernet
(Internet) port on the back panel of the eMTA and connect the
other end to an Ethernet port on a wireless router (or other
Ethernet-enabled device).
FRONT PANEL:
Reset: Use to reset the device settings. When the Reset button
icon, and the surrounding ring are illuminated, press and hold the
button for 4 seconds to initiate a power cycle. If the lights are not
lit, the device can be factory reset. Press and hold the button for
10 seconds to reset the device to factory default settings. Note:
When the button and ring are lit, a power cycle must be performed
prior to performing a factory reset.

REAR PANEL:
Ethernet (Internet): Connect to an Ethernet-enabled device such
as a wireless access point (router) using an RJ45 Ethernet cable.
Voice 1-2: Use to connect analog telephones to the device.
Telephone service must be enabled by the service provider.
Cable: Use to connect to the coaxial cable from your Internet
service provider.
Power: Use to connect to the power adapter. Plug the other end
into the wall power outlet.

3. Connect an RJ-11 phone cable (not supplied) to the Voice 1 or 2
port on the modem (when provisioned for voice service as
specified by the service provider), and connect the other end to
the phone port of the telephone. If voice service is not
provisioned through the service provider, telephone service is not
available.
4. Connect the power adapter (supplied) to the Power port on the
modem. Connect the other end to a power outlet.

!
To mount the device on a wall:
1. Install the 2 screws horizontally on the wall 140 mm (5.51
inches) apart.
You can mount the E31U2V1 on a wall using the 2 mounting
brackets on the side of the device. Two round or pan head screws
are recommended. See the figure below for measurements.
3
Note: The screws should protrude from the wall so you can fit
the device between the head of the screws and the wall. If you
install the screws in drywall, use hollow wall anchors to ensure
the unit does not pull away from the wall due to prolonged
strain from the cable and power connectors.
2. Mount the device on the wall
