Local Cable Network Service
Prepare Your Workspace 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.
6
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
remoteconfiguration and monitoringfrom amanagement station equippedwith
an SNMP server.

Features
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 Usingthe Ethernet Port”, or see“Installing the
CableModem Using theUSB Port” inthe following pages,for more information.
