Restoring Factory Defaults

The Reset button on the rear 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 “Reboot Menu” on page 79) or return the Gateway to its factory default settings (see “Restoring Factory Defaults” on page 77).

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 rear panel, then press and hold it for at least 10 seconds.

3. Release the Reset button.

Rebooting the Gateway

If the Gateway has problems connecting to the Internet, hold down the Reset button on the rear panel for 1 second and then release.

2 Installing the Gateway

This chapter describes how to install the SMC8014WN and SMC8014WN2 Wireless Cable Modem Gateways. 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 Gate way (page 18)

SMC8014WN and SMC8014WN2 Wireless Cable Modem Gateway Administrator Manual

錯誤! 尚未定義樣式。

Finding a Suitable Location

The Gateways 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 airflow 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, insula ted 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 PC or notebook computer, hub, or switch. The Gateways support auto-MDI/MDIX, so you can use either a standard straight-throu gh or cr o ssov e r Et he r net ca bl e.

1. Connect either end of an Ethernet cable to one of the four LAN ports on the rear panel of the Gateway (see Figure 5).

Figure 5. Connecting to a LAN 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 6).

錯誤! 尚未定義樣式。

Figure 6. Connecting the Gateway to the a Laptop or Desktop Computer

Connecting the WAN

To connect the Gateway to a Wide Area Network (WAN) interface:

1. Connect a coaxial cable to the port labeled CATV on the rear panel of the Gateway from a cable port in your home or office (see Figure 2 on page 6 or Figure 4 on page 14). Use only manufactured coaxial patch cables with F-type connectors at both ends for all connections.

2. 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 6 or Figure 4 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 11 or Table 3 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.
