Using the Reset Button
Using the reset button on the rear panel (see Figure 2 on page 15), you can perform two
types of reset operations with the Gateway:
Software reset – this reset operation power-cycles the Gateway and retains its current
configuration settings.
Factory default reset – this operation remove all overrides made to the Gateway’s factory
default configuration and returns the Gateway to its original factory default settings.
The number of seconds you press the reset button determines which reset operation is
performed. To protect against accidental resets, the reset button is recessed on the
Gateway rear panel.
Note: You can also reset the Gateway and retain its current configuration settings using the
RESET method described under “Restoring or Rebooting the Gateway” on page 98.
。。。。
To use the reset button to perform a software or factory default reset:
1. Leave power plugged into the Gateway.
2. Find the reset button at the top of the back panel, then use a thin object to press and hold
the reset button as follows:
– To perform a software reset, press the reset button for at least 10 seconds.
– To perform a factory default reset, press the reset button for at least 15 seconds.
3. Release the reset button.

。。
Finding a Suitable Location
Your SMCD3GNV3 Wireless Cable Modem Gateway can be installed in any location with
access to the cable network. All of the cables connect to the rear panel of the Gateway for
better organization and utility. The LED indicators on the front panel are easily visible to
provide you with information about network activity and status.
For optimum performance, the location you choose should:
Be close to a working AC power outlet when powering the Gateway using AC power.
Allow at least one foot of space around the sides and top of the Gateway to provide
sufficient air flow around the device.
Not expose the Gateway to a dusty or wet environment.
Be an elevated location such as a high shelf, keeping the number of walls and ceilings
between the Gateway and your other devices to a minimum.
Be away from electrical devices that are potential sources of interference, such as ceiling
fans, home security systems, microwaves, or the base for a cordless phone.
Be away from any large metal surfaces, such as a solid metal door or aluminum studs.
Large expanses of other materials such as glass, insulated walls, fish tanks, mirrors,
brick, and concrete can also affect your wireless signal. For more information about
selecting an optimum location for wireless operation, see “Guidelines for Improving Your
Wireless Network” on page 201.

1. Place the Gateway on its side on a table.
2. Remove battery compartment door on the bottom panel and set it aside (see Figure 4).
Figure 4. Removing the Battery Compartment Door
3. Insert the battery into the battery compartment (see Figure 5).
Figure 5. Installing the Battery
4. Close the battery compartment.
Note: Using the Battery menu in the Gateway’s Web interface, you can view status
information about the battery (see “Viewing Battery Settings” on page 57).

Connecting to the LAN
Using an Ethernet LAN cable, you can connect the Gateway to a desktop computer,
notebook, hub, or switch. The Gateway supports auto-MDI/MDIX, so you can use either a
standard straight-through or crossover Ethernet cable.
1. Connect either end of an Ethernet cable to one of the four Ethernet ports on the rear panel
of the Gateway (see Figure 6).
Figure 6. Connecting to an Ethernet Port on the Gateway Rear Panel
2. Connect the other end of the cable to your computer’s network-interface card (NIC) or to
another network device (see Figure 7).

Connecting the WAN
To connect the Gateway to a Wide Area Network (WAN) interface:
3. Connect a coaxial cable to the port labeled Cable on the rear panel of the Gateway from a
cable port in your home or office (see Figure 2 on page 15). Use only manufactured coaxial
patch cables with F-type connectors at both ends for all connections.
4. Hand-tighten the connectors to secure the connection.
5. If the modem was not installed by your cable provider (ISP) or is replacing another cable
modem, contact your cable operator to register the SMCD3GNV3. If the modem is not
registered with your cable operator, it will be unable to connect to the cable network
system.
Connecting to the Public Telephone Network
The rear panel of the Gateway has two RJ-11 telephone-style connectors labeled Tel 1 and
Tel 2. Each of these connectors can provide telephone service to multiple telephones, fax
machines, and analog modems.
The maximum number of telephone devices connected to each RJ-11 port is limited by the
total Ringing Load of the telephone devices that are connected. Many telephone devices are
marked with a Ringer Equivalent Number (REN). Each telephone port on the Gateway can
support up to a 5 REN load. The sum of the REN load on all of the telephone devices
attached to each port must not exceed 5 REN
Before you use the Gateway’s RJ-11 connectors to power the analog devices in your home
or office, disconnect the telephone lines from any other provider at the demarcation point. If
the incoming phone line is connected to another provider, such as an incumbent telephone
company, it can result in potentially harmful voltage to the analog telephone line.
Note: The customer or the customer's wire contractor is responsible for adhering to all local
codes for wiring.
To set up the ability to place calls using a regular analog telephone line (PSTN), perform the
following procedure.
1. Disconnect the phone lines from any other provider at the demarcation point, if appropriate.
2. Connect the RJ-11 cable on an analog device to the Tel 1 connector on the rear panel of
the Gateway.
3. Connect the RJ-11 cable on another analog device to the Tel 2 connector on the rear
panel of the Gateway.
