Spectrum E31U2V1 Advanced Voice Modem
SAFETY NOTICES
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 a 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.).
PREPARING FOR INSTALLATION
Verify package contents, RF cable connectors, and power outlet.
Unpack the box and confirm the following components:
- Locate the RF (coaxial) cable connector on the wall.
- Verify the power outlet is working and is wired correctly. Place your eMTA within a proper distance from the outlet.

-
Generate a Password of the Day (PoTD) using the PoTD tool.
-
Enable HTTP/HTTPs using RIO or DRUM.
-
Use IPv4 or IPv6 to remotely access the UI of the E31U2V1 DOCSIS 3.1 eMTA.
- IPv4: WAN side via the RF CM IPv4 address. Example: HTTP://10.11.12.13
- IPv6: WAN side via the RF CM IPv6 address.
Example: HTTP://[2001:b021:15:7a00:dc4d:dc7c:467c: 4dfb]

UNDERSTANDING DEVICE CONNECTIONS
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.
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.
INSTALLING THE MODEM
- 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 television to the same wall outlet, you must use a cable line splitter (not included).
- 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 another Ethernet-enabled device).
- 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.
- Connect the power adapter (supplied) to the Power port on the modem. Connect the other end to a power outlet.
INSTALLATION DIAGRAM
DEVICE WALL MOUNT INSTRUCTIONS
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.
Label | Size in Millimeters (mm) |
---|---|
A | 9.5 +/- 0.2 |
B | 3.7 +/- 0.1 |
C | 34.5 +/- 0.2 |
To mount the device on a wall:
-
Install the 2 screws horizontally on the wall 140 mm (5.51 inches) apart.
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. -
Mount the device on the wall
NOTE to CATV SYSTEM INSTALLER:
This reminder is provided to call the CATV systems installer’s attention to
section 820-93 of the National Electric Code, which provides guidelines for
proper grounding and in particular, specifies that the Coaxial cable shield
shall be connected to the grounding system of the building, as close to the
point of cable entry as practical.
