This Quick Start provides basic instructions for connecting the ADSL Barricade to a computer or LAN and to the Internet.

•

Connecting the Hardware describes how to set up the hardware.

•

Configuring Your Computers describes how to configure Internet properties on your computer(s).

•

Configuring the ADSL Barricade shows you how to configure basic settings on the ADSL Barricade to get your LAN

connected to the Internet.

After having set up and configured the device, please follow the instructions on page 21 to check whether it is working properly.

This Quick Start assumes that you have already established an ADSL service with your Internet service provider (ISP). These instructions provide a basic configuration that should be compatible with your home or small office network setup. Refer to the subsequent chapters for additional configuration instructions.

TART

Connecting the Hardware

You connect the device to the wall phone jack, the power outlet, and your computer or network.

Warning:

Before you begin, turn the power off for all devices. These include your computer(s), your LAN hub/ switch (if applicable), and the ADSL Barricade.

Figure 1. Overview of Hardware Connections

Step 1. Connect the ADSL cable

Connect one end of the provided phone cable (RJ-11) to the port labeled DSL on the Rear Panel of the device. Connect the other end to your wall phone jack.

You can attach a telephone line to the device. This is helpful when the ADSL line uses the only convenient wall phone jack. If desired, connect the telephone cable to the port labeled Phone.

Warning:

Although you use the same type of cable, the ADSL and Phone ports are not interchangeable. Do not route the ADSL connection through the Phone port.

Note:

ADSL splitters/microfilters are included with some models.

Configuring Your Computers

Step 2. Connect the Ethernet cable

If you are connecting a LAN to the ADSL Barricade, attach one end of a provided Ethernet cable to a regular hub port and the other to the Ethernet port on the ADSL Barricade. If you are using the ADSL Barricade with a single computer and no hub, you must use an Ethernet cable to attach the PC directly to the device. The cable is wired differently than the cable you would use to connect to a hub.

Step 3. Attach the power connector

Connect the AC power adapter to the Power connector on the back of the device and plug in the adapter to a wall outlet or power strip.

Step 4. Power up your systems

Turn on and boot up your computer(s) and any LAN device such as hubs or switches.

Configuring Your Computers

This section provides instructions for configuring settings on your computers to work with the ADSL Barricade

Before you begin

By default, the ADSL Barricade automatically assigns all required Internet settings to your PCs. You need only to configure the PCs to accept the information when it is assigned.

Quick Start

Assigning static Internet Information to your PCs

In some cases, you may want to assign Internet information to some or all of your PCs directly (often called statically), rather than allowing the ADSL Barricade to assign it. This option may be desirable (but not required) if:

•

You have obtained one or more public IP addresses that you want to associate with specific computers (for example,

if you are using a computer as a public web server).

•

You maintain different subnets on your LAN (subnets are described in IP Addresses, Network Masks, and Subnets).

Before you begin, be sure to have the following information on hand (or contact your ISP if you do not know it):

•

The IP address and subnet mask you will assign to each PC which will be assigned static IP information.

•

The IP address of the default gateway for your LAN. In most

cases, this is the address assigned to the LAN port

. By default, the LAN port is assigned

192.168.1.1.] (You can change this number, can be assigned by your ISP.) See

•

The IP address of your ISP's Domain Name System (DNS) server.

On each PC you will assign static information, follow the instructions on pages 9 through 15 specific to the IP protocol.

Configuring the ADSL Barricade

Note:

Your PCs must have IP addresses that place them in the same subnet as the ADSL Barricade's LAN port. If you manually assign IP information to all your LAN PCs, you can follow the instructions in Configuring the LAN Ports to change the LAN port IP address accordingly.

Configuring the ADSL Barricade

This section provides you instructions on how to log into the program of the ADSL Barricade and how to configure basic settings for your Internet connection. Your ISP should provide you with the necessary information to complete this step.

Logging into the ADSL Barricade Quick Configuration Page

The ADSL Barricade provides a preinstalled software program called Configuration Manager which enables you to configure the operation of the device via your Web browser. The settings that you most likely need to change before using the device are grouped onto one single [Quick Configuration] page.

Follow these instructions to configure the device settings.

At any PC connected to the ADSL Barricade via Ethernet or USB, open in the address/location box: 192.168.1.1/setup. Username/ Password: smc/smcadmin.

When you press [Enter], the page shown in Figure 2 should appear (see section Troubleshooting on page 175, if you receive an error message or if the page does not appear).
