removing the cover may expose you to dangerous voltages. If you open the cover, your
warranty will be void. This product contains no user-serviceable parts. Refer all
servicing to qualified service personnel.
Servicing is required when the apparatus has been damaged in any way, such as a power-supply cord
or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has
been exposed to rain or moisture, does not operate normally, or has been dropped.
Check Product Safety
Upon completion of any service or repairs to this product, the service technician must perform safety
checks to determine that this product is in proper operating condition.
Protect the Product When Moving It
Always disconnect the power source when moving the apparatus or connecting or disconnecting
cables.
WARNING: Avoid personal injury and damage to this product! Use only with the cart,
stand, tripod, bracket, or table specified by the manufacturer or sold with the

How Do I Set Up My High-Speed Internet Access Account?
How Do I Set Up My High-Speed Internet Access Account?
Before you can use your cable modem, you need to have a high-speed Internet
access account. If you do not have a high-speed Internet access account, you need to
set up an account with your local service provider. Choose one of the two options in
this section.
I Do Not Have a High-Speed Internet Access Account
If you do not have a high-speed Internet access account, your service provider will
set up your account and become your Internet Service Provider (ISP). Internet access
enables you to send and receive e-mail, access the World Wide Web, and receive
other Internet services.
You will need to give your service provider the following information:
The serial number of the modem
The Media Access Control (MAC) address of the modem
These numbers appear on a bar code label located on the cable modem. The serial
number consists of a series of alphanumeric characters preceded by S/N. The MAC
address consists of a series of alphanumeric characters preceded by CM MAC. The
following illustration shows a sample bar code label.
Write down these numbers in the space provided here.
Serial Number _______________________
MAC Address ________________________
I Already Have an Existing High-Speed Internet Access Account
If you have an existing high-speed Internet access account, you must give your
service provider the serial number and the MAC address of the cable modem. Refer
to the serial number and MAC address information listed previously in this section.
Note: You may not be able to continue to use your existing e-mail account with your
cable modem. Contact your service provider for more information.

How Do I Connect My Devices to Use the Internet?
Connecting the Modem for High-Speed Data Service
WARNING:
To avoid personal injury or damage to your equipment, follow these steps in
the exact order shown.
1Power off your PC and unplug it from the power source.
2Connect your PC to either the ETHERNET port or the USB port using the
appropriate data cable. Do not connect your PC to both the Ethernet and USB
ports at the same time. You can connect two separate PCs to the cable modem at
the same time by connecting one PC to the Ethernet port and one PC to the USB
port.
3Connect the active RF coaxial cable to the CABLE connector. Use an optional
cable signal splitter to add a TV, a DHCT or set-top converter, or a VCR.
4Insert the AC power cord into the POWER connector on the back of the cable
modem, and then plug the cord into an AC power source.
5Plug in and power on your networked devices including your PC. The cable
modem will then begin an automatic search to locate and sign on to the
broadband data network. This process may take up to 5 minutes. The modem
will be ready for use when the ONLINE LED status indicator on the front panel
stops blinking and illuminates continuously.
6The next step in setting up your cable modem is to configure your Internet
devices for Internet access. Choose one of the following options:
If you want to use Ethernet connections, you must configure the TCP/IP
protocol. To configure the TCP/IP protocol, go to How Do I Configure
TCP/IP Protocol? (on page 19).
If you want to use USB connections, you must install the USB drivers. To
install the USB Drivers for USB, go to How Do I Install USB Drivers? (on
page 22).
