Front Panel Description

The front panel of your cable modem provides status lights that indicate how well and at what state your cable

modem is operating. After the cable modem is successfully registered on the network, the POWER and CABLE

status indicators illuminate continuously to show that the cable modem is active and fully operational. See Front

Panel Status Indicator Functions, later in this guide, for more information on front panel status indicator

functions.

The following illustration and descriptions of the status indicators apply to the Model DPX100/120 Cable Modems

along with the Model DPX2100 and Model EPX2100 Cable Modems.

Model DPX100/120 Cable Modems support DOCSIS 1.0 and 1.1 and Euro-DOCSIS 1.0 and 1.1, while

Model DPX2100 and Model EPX2100 Cable Modems support DOCSIS 2.0.

Where is the Best Location for My Cable Modem?

The ideal location for your cable modem is where it has access to outlets and other devices. Think about the

layout of your home or office, and consult with your cable service provider to select the best location for your

cable modem.

Consider these recommendations:

 Position your PC and cable modem so that they are located near an AC

power outlet.

 Position your PC and cable modem so that they are located near an existing

cable input connection to eliminate the need for an additional cable outlet.

There should be plenty of room to guide the cables away from the modem

and the PC without straining or crimping them.

 Airflow around the cable modem should not be restricted.

 Choose a location that protects the cable modem from accidental

disturbance or harm.

 Read this user’s guide thoroughly before you decide where to place your

cable modem.

What are the System Requirements for Internet Service?

To ensure that your cable modem operates efficiently for high-speed Internet service, verify that all of the Internet

devices on your system meet or exceed the following minimum hardware and software requirements.

You will also need an active cable input line and an Internet connection.

Minimum System Requirements for PCs

 A PC with a Pentium MMX 133 processor or greater

 32 MB of RAM

 Web browsing software (Netscape or Internet Explorer)

 CD-ROM drive

Minimum System Requirements for Macintosh

 MAC OS 7.5

 32 MB of RAM

System Requirements for an Ethernet Connection

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 a high-speed Internet access account with your

local cable service provider. Choose one of the following two options.

I Do Not Have a High-Speed Internet Access Account

If you do not have a high-speed Internet access account, your cable service

provider will set up your high-speed Internet access 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. When

you contact your cable service provider, they will ask you for the serial number

and Media Access Control (MAC) address of the cable modem.

These numbers appear on a bar code label located on the side of 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 MAC.

Write down these numbers in the space provided here.

Serial Number _______________________

MAC Address ________________________

The following illustration shows a sample bar code label.

I Already Have an Existing High-Speed Internet Access Account

If you have an existing high-speed Internet access account, you must give your

cable 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.

You may be able to continue to use your existing e-mail account with your

cable modem. Contact your cable service provider for more information.

How Do I Connect My Devices to Use the Internet?

You can use your cable modem to access the Internet, and you can share that Internet connection with other

Internet devices in your home or office. Sharing one connection among many devices is called networking.

Connecting and Installing Internet Devices

You must connect and install your cable modem to access the Internet.

Professional installation may be available. Contact your local cable service

provider for further assistance.

To connect devices

The following diagram illustrates one of the various Internet connection options

that are available to you.
