Chapter 2 Before You Begin
Before installation, please check the following requirements with your computer.
This cable modem equips ETHERNET and USB (optional) interfaces. You can
choose either one to connect to the cable modem or connect Ethernet and USB
simultaneously.
2.1 System Requirements System Requirement of Ethernet Connection
1. IBM Compatible, Macintosh or other workstation supports TCP/IP protocol.
2. An Ethernet port supports 10Base-T/100Base-TX Ethernet connection.
3. Subscribed to a Cable Television company for Cable Modem services.
System Requirement of USB Connection ( optional )
1. IBM Compatible PC with Microsoft Windows 98/2000/Me/XP.
2. PC with available USB Port.
3. Subscribed to a Cable Television company for Cable Modem services.
If using a MSO network, contact your local cable operator to ensure the termination
circuit is removed and service is available.
2.2 Safety Precautions
For your protection, observe the following safety precautions when setting up and
using your equipment. Failure to observe these precautions can result in serious
personal injury and damage to your equipment.
• Make sure the voltages and frequency of the power outlet match the electrical rating
labels on the AC Adapter.
• Do not place any object on top of the device or force it into a confined space.
• Never push objects of any kind through openings in the casing. Dangerous voltages
may be present. Conductive foreign objects could produce a short circuit that could

DOCSIS 1.0/ 1.1 Equivalent Cable Modem
cause fire, electrical shock, or damage to the equipment.
• When installing the CABLE MODEM, be sure to observe the anti-static caution in
the installation section of this user’s guide. This will prevent damage to the board
and other components.
• Whenever there is danger of lightning, disconnect the power cable and the
Hybrid-Fiber Coax cable from the cable modem to prevent damage to the unit. The
use of an AC protection device will not completely protect the cable modem product
from damage caused from the transmission across the Hybrid-Fiber Coax network.
2.3 Unpacking and Inspection
Included in the kit is the following:
• Cable Modem
• AC Adapter
• Installation Guide
• Ethernet RJ-45 Cable

Chapter 3 Hardware Installation
This chapter describes the proper steps for connecting your new Cable Modem. Please
be sure to follow the steps in the sequence outlined below. Failure to do so could result
in improper operation or failure of your Cable Modem.
Step 1:
Connect a DOCSIS 1.0/1.1 equivalent cable feed to the F-connector on the back of the
cable modem as illustrated in Figure 1. Ensure that the center conductor of the 75 ohm
coaxial cable is inserted directly into the center of the F-connector. Secure the coaxial
cable by carefully threading the outer shell of the coaxial cable connector onto the
F-connector in a clockwise direction until tight. Be careful not to over-tighten the
connector or you may damage either the connector or the cable modem.
NOTE: To speed up the initial cable modem registration process, the coaxial cable
should be connected to the modem prior to the power connector.

Cable Feed (F Connector)
Step 2:
Connect the AC Adapter to the Cable Modem by inserting the barrel-shaped connector
into the mating power connector on the back of the Cable Modem as illustrated in
Figure 2. Exercise carefully to ensure the connectors are properly aligned prior to
insertion and ensure the two connectors engage completely. The cable modem is
shipped with an AC adapter. Remember to use only power adapter that came with
the cable modem. Other power adapters might have voltages that are not correct for
your particular cable modem. Using a power adapter with the wrong voltage can
damage the cable modem. The cable modem power input requires 12 VDC input
with minimum 1000 mA current. The +12 V is on the center connector, and ground is
on the outer connector.

Step 3-a:
Connect the Cable Modem to an IEEE 802.3 10BaseT / 802.3u 100Base-TX Network
using a RJ-45 male-terminated CAT-5 cable as illustrated in Figure 3a.

Auto-MDIX Ethernet
Step 3-b (optional):
Notice: Some serials may not have USB port.
Connect the USB cable to the Cable Modem by inserting the rectangular end of an
USB cable into the USB port of the Cable Modem as illustrated in Figure 3b. Ensure
the connectors lock together by listening for a snap.

CAUTION 1: Connecting to More Than one Computer Devices:
This cable modem provides you the feature for Ethernet and USB interfaces to operate
on 2 different computer devices simultaneously. However, you have to obtain
additional IP addresses from your cable service provider.
CAUTION 2: Do not using USB and Ethernet in one computer at the same time.
You are strongly recommended to connect to the Internet using either the Ethernet
port or the USB port only. In most cases CATV ISPs provide one IP address only,
having the USB and Ethernet cables plugged into the cable modem at the same time
might cause you to access the Internet improperly.
