Configuring Wireless Security
The front panel has a WPS button for configuring wireless security automatically. Pressing
this button for 5 seconds automatically configures wireless security. If the client device
supports WPS Push Button Configuration (PBC), press the button on the client within 60
seconds to automatically configure security on the client.
After pressing this button for 5 seconds, the WPS LED on the front panel flashes. When a
client joins the network successfully, the LED remains ON until the next WPS action or the
device reboots. If no client joins, the LED stops blinking after 4 minutes.
Rear Panel
The rear panel of the SMCD3GN3 Wireless Cable Modem Gateway contains a reset button
and the ports for attaching the supplied power adapter and making additional connections.
Figure 2 shows the rear panel components and Table 2 describes their meanings.

Restoring Factory Defaults
The Reset button on the back panel can be used to return the Gateway to its factory default
settings. As a result, any changes made to the Gateway’s default settings will be lost.
If you do not have physical access to the Gateway, you can use the GUI to either power
cycle the Gateway (see “Using the Reboot Menu to Reboot the Gateway” on page 137) or
return the Gateway to its factory default settings (see “Restoring Factory Defaults” on page
136).
The following procedure describes how to use the Reset button to power cycle the Gateway
and return it to its original factory default settings.
1. Leave power plugged into the Gateway.
2. Find the Reset button on the back panel, then press and hold it for at least 10 seconds.
3. Release the Reset button.

2 Installing the Gateway
This chapter describes how to install the SMCD3GN3 Wireless Cable Modem Gateway. The
topics covered in this chapter are:
y Finding a Suitable Location (page 17)
y Connecting to the LAN (page 17)
y Connecting the WAN (page 18)
y Powering on the Gateway (page 18)
16
SMCD3GN2 Wireless Cable Modem Gateway Administrator Manual
錯誤! 尚未定義樣式。
Finding a Suitable Location
The SMCD3GN3 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 users with information about network activity and status.
For optimum performance, the location you choose should:
y Be close to a working AC power outlet
y Allow sufficient air flow around the Gateway to keep the device as cool as possible
y Not expose the Gateway to a dusty or wet environment
y 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
y 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
y 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
Connecting to the LAN
Using an Ethernet LAN cable, you can connect the Gateway to a desktop computer,
notebook, hub, or switch. The SMCD3GN3 Wireless 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 ETH ports on the rear panel of
the Gateway (see Figure 3).
Figure 3. Connecting to an ETH Port on the Gateway Rear Panel
17
SMCD3GN2 Wireless Cable Modem Gateway Administrator Manual
錯誤! 尚未定義樣式。
2. Connect the other end of the cable to your computer’s network-interface card (NIC) or to
another network device (see Figure 4).
Figure 4. Connecting the Gateway to the a Laptop or Desktop Computer
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 14). 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.
Powering on the Gateway
After making your LAN and WAN connections, use the following procedure to power on the
Gateway:
1. Connect the supplied power cord to the port on the rear panel of the Gateway (see Figure
2 on page 14).
2. Connect the other end of the power cord to a working power outlet. The Gateway powers
on automatically, the POWER LED on the front panel goes ON, and the other front panel
LEDs show the Gateway’s status (see Table 1 on page 13).
WARNING: Only use the power cord supplied with the Gateway. Using a different
power cord can damage the Gateway and void the warranty.
