access. Your local cable operator will check for cable access availability in your area, install a cable line (if necessary), provide you with an access account, set up configuration and verify other technical details.

4 Ask your local cable service provider about adding additional IP addresses to your account. See “ Which Installation to Use?” for more information.

Prepare Your Worksp ace for the Cable Modem Installation

Before installing the cable modem, you should prepare your workspace. You can install the cable modem vertically, or attach the included four rubber feet and install the cable modem horizontally.

To prepare your workspace: 1 Position the cable modem so that it is located near the computer and the

wall cable outlet. There should be plenty of room to guide the cables away from the cable modem without crimping them.

2 Prepare the cable modem:



For vertical installation: Place the cable modem securely in the included stand. For horizontal installation: Use the four included feet to install the



cable modem.

Prepare Your Worksp ace for the Cable Modem Installation (continued)

Remove the backing paper and attach a foot to each of the corners on the cable modem; be sure to attach the feet on the surface that contains the model information stickers, as shown.

3 Do not restrict the airflow around the cable modem. 4 To enhance the best performance and proper function of the cable

modem, place it on a horizontal surface or workplace and make sure that the cable modem does not move when it is operating.

Introduction

Thank you for purchasing the D-Link “Broadband Cable Modem with USB & Ethernet” DCM-202, which is an MCNS DOCSIS™ 2.0 cable modem featuring the latest DOCSIS technology .

The cable modem enables your network cable operator to provide you with broadband applications such as telecommunications, IP dedication for your small office/home office (SOHO), or high-speed residential Internet access. The cable modem provides a downstream speed of up to 38Mbps from the cable network to your computer and 30Mbps from your computer to the cable network.

The DES data encryption helps ensure privacy for the transmitted information. Another distinctive feature of the cable modem is its easy installation, because DHCP and TFTP clients can obtain automatic access to the IP address and configuration from their network servers via the modem. SNMP agents permit remote configuration and monitoring from a management station equipped with an SNMP server .

Decide Which Installation Process to Use

The cable modem enables you to connect to the Internet using either your computer’s Ethernet or USB port.

Be sure to follow the installation steps for the setup you want to use. Using the Ethernet setup enables you to use a hub to connect multiple computers to the cable modem. To do this, you might have to obtain additional IP addresses from your cable operator.

Using the USB port enables you to install the cable modem more quickly and easily than connecting to the Internet using the Ethernet port, because you do not have to install a network interface card (NIC) into your computer . The USB port, however, only enables you to connect one computer to the cable modem.

See “Installing the Cable Modem Using the Ethernet Port”, or see “Installing the Cable Modem Using the USB Port” in the following pages, for more information.
