Where Is the Best Location for My Cable Modem Gateway?

The ideal location for your cable modem gateway is where it has access to outlets and other devices. Think about the layout of your home or office, and consult with your service provider to select the best location for your cable modem gateway. Read this user's guide thoroughly before you decide where to place your cable modem gateway.

Consider these recommendations:

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

power outlet.

 Position your PC and cable modem gateway 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 gateway should not be restricted.

 Choose a location that protects the cable modem gateway from accidental

disturbance or harm.

4011533 Rev A 17

What Are the System Requirements for Internet Service?

To ensure that your cable modem gateway 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.

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

Minimum System Requirements for a PC

 A PC with a Pentium MMX 133 processor or greater

 32 MB of RAM

 Web browsing software

 CD-ROM drive

Minimum System Requirements for Macintosh

 MAC OS 7.5

 32 MB of RAM

System Requirements for an Ethernet Connection

 A PC with Microsoft Windows 95 operating system (or later) with TCP/IP

protocol installed, or an Apple Macintosh computer with TCP/IP protocol installed

 An active 10/100BaseT Ethernet network interface card (NIC) installed

System Requirements for a USB Connection

 A PC with Microsoft Windows 98SE, ME, 2000, or XP operating system

 A master USB port installed in your PC or your Apple Macintosh computer

18 4011533 Rev A

How Do I Set Up My High-Speed Internet Access Account?

Before you can use your cable modem gateway, 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 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 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

 The WLAN data MAC address of the modem

These numbers appear on a bar code label located on the cable modem gateway. 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. The WAN Data MAC address consists of a series of alphanumeric characters preceded by WAN DATA MAC. See the following illustration of a sample label. The following illustration shows a sample bar code label.

Write down these numbers in the space provided here.

Serial Number _______________________

MAC Address ________________________

WAN DATA MAC Address ________________________

4011533 Rev A 19

How Do I Set Up My High-Speed Internet Access Account?

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 addresses of the cable modem gateway. 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 gateway. Contact your service provider for more information.

20 4011533 Rev A

How Do I Connect My Devices to Use the Internet?

You can use your cable modem gateway 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 gateway to access the Internet. Professional installation may be available. Contact your local service provider for further assistance.

To connect devices

The following diagram illustrates one of the various connection options that are available to you.

Note: The DPR2320 and EPR2320 models have only one (1) Ethernet port.

4011533 Rev A 21

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.

1 Power off your PC and unplug it from the power source.

2 Connect 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 gateway at the same time by connecting one PC to the Ethernet port and one PC to the USB port.

3 Connect 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.

4 Insert the AC power cord into the POWER connector on the back of the cable

modem gateway, and then plug the cord into an AC power source.

5 Plug in and power on your networked devices including your PC. The cable

modem gateway 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.

6 The next step in setting up your cable modem gateway 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

23).

 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

26).

22 4011533 Rev A

How Do I Configure TCP/IP Protocol?

To configure TCP/IP protocol, you need to have an Ethernet Network Interface Card (NIC) with TCP/IP communications protocol installed on your system. TCP/IP is a communications protocol used to access the Internet. This section contains instructions for configuring TCP/IP on your Internet devices to operate with the cable modem gateway in Microsoft Windows or Macintosh environments.

Configuring TCP/IP on Your Internet Devices

What Are the Requirements for Ethernet Network Devices?

How Many Ethernet Network Devices Can I Connect?

The Scientific Atlanta cable modem gateway can support several Ethernet network devices using external Ethernet hubs that must be purchased separately.

The theoretical maximum number of Ethernet network devices supported is by the cable modem gateway is 63. However, under normal circumstances, the number of devices connected should be a much lower number.

Contact your service provider for more information on the maximum number of Ethernet network devices to connect to your cable modem gateway to maintain optimal network performance.

What Are the Wiring Requirements for Ethernet Networking?

A number of factors can impact the practical limit of the network. Although the cable modem gateway is designed to support several Ethernet network devices, it is important to view the characteristics of the entire network and not just each individual node.

The theoretical distance between two 10/100BaseT CAT-5 Ethernet hubs is 382 feet (100 meters). Contact your service provider or consult the documentation for your Ethernet network devices for more information.

Note: Scientific Atlanta recommends that you use CAT-5 Ethernet cables.

Do I Need to Configure the TCP/IP Protocol on My Computer?

For you to use Ethernet network devices on your network, you must have the TCP/IP protocol properly configured on your PC. Refer to How Do I Configure TCP/IP Protocol? (on page protocol.
