Getting to Know the Cable Modem with USB and Ethernet Connection

Overview

A "Cable Modem" is a device that allo ws high-speed data access (such as to the Internet) via a cable TV network. A cable modem will typically have two connections, one to the cable wall outlet and the other to a computer (PC). The fact that the word "modem" is used to describe this device can be a little misleading only in that it conjures up images of a typical telephone dial-up modem. Yes, it is a modem in the true sense of the word since it MOdulates and DEModulates signals. However, the similarity ends there, as these devices are much more complicated than telephone modems. Cable modems can be part modem, part tuner, part encryption/decryption device, part bridge, part router, part network interface card, part SNMP agent, and part Ether net hub.

Cable modem speeds vary, depending on the cable modem system, cable network architecture, and traffic load. In the downstream direction (from the network to the computer), network speeds can reach 27 Mbps, an aggregate amount of bandwidth that is shared by users. Few computers will be capable of connecting at such high speeds, so a more realistic number is 1 to 3 Mbps. In the upstream direction (from computer to network), speeds can be up to 10 Mbps. However, most modem producers have selected a more optimum speed between 500 Kbps and 2.5 Mbps. Some service providers limit upstream access speeds to 256 Kbps or less. Check with your Cable Internet Service Provider for more information about upload (upstream) and download (downstream) access speeds for more specific infor mation.

In addition to speed, there's no need to dial in to an Internet service provider (ISP) when you are using your Cable Modem. Simply click on your browser and you're on the Internet. No more waiting, no more busy signals.

Overview

EtherFast®Cable Modem with USB and Ethernet Connection

The Cable Modem with USB and Ethernet Connection’s

Rear Panel

Cable Port The cable from your Internet Service

Provider connects here. It is a round coaxial cable, exactly like the one that connects to the back of your cable box (if you have one), or like the one that probably connects your VCR to your television.

USB Port This port allows you to connect your

Cable Modem to your PC using the included USB cable. Not all computers are able to use USB connections. For more information concerning USB and compatibility with your computer, see the next section.

Ethernet Port This port allows you to connect your

Cable Modem to your PC or other Ethernet network device using a UTP Category 5 (or better) network cable.

Reset Button Briefly pressing and holding in the

Reset button allows you to clear the Cable Modem’s connections if there are any data “jams” and resets the Modem to the factory defaults. Continued or repeated pressing of this button is not recommended.

Powe r Port The Power port is where the included

power adapter is connected to the Cable Modem.

The Rear Panel

The USB CABLE Icon

The USB icon shown below marks a USB port on a PC or device.

To use this USB device, you must have Windows 98, 2000, or Millennium installed on your PC. If you do not have Windows 98, 2000, or Millennium, this device will not work.

Also, this device requires that a USB port is installed and enabled on your PC. Some PCs have a disabled USB port. If your port doesn’t seem to be working, there may be motherboard jumpers or a BIOS menu option that will enable the USB port. See your PC’s user guide for details.

Some motherboards have USB interfaces, but no ports. You should be able to install your own USB port and attach it to your PC’s motherboard using hardware purchased at most computer stores.

Your Cable Modem with USB and Ethernet Connection comes with a USB cable that has two different types of connectors. Type A, the master connector, is shaped like a rectangle and plugs into your PC’s USB port. Type B, the slave connector, resembles a square and connects to the USB port on the rear panel of your Cable Modem.

USB Type A

USB Type B

There is no USB Support on PCs run-

ning Windows 95 or Windows NT.

Connecting the Cable Modem with USB to Your PC

Connecting Using the Ethernet Port

1. Make sure that you have TCP/IP installed on your computer. If you don’ t

know what TCP/IP is or you don’t have it installed, refer to the section in the Appendix called Installing the TCP/IPProtocol.

2. Connect the coaxial cable from your Internet Service Provider/Cable Company to the Cable Port on the back of the Cable Modem. The other end of the coaxial cable should be connected in the manner proscribed by your Internet Service Provider/Cable Company.

3. Connect a UTP Category 5 (or better) Ethernet cable to the Ethernet Port on the back of the Cable Modem. Connect the other end of the cable to the RJ-45 port on your computer’s Ethernet adapter or your hub/switch/router.

4. With your PC turned off, connect the power adapter included in your package to the Power P ort on the back of the Cable Modem. Plug the power cord into the pow er adapter. Plug the other end of the power cord into a standard electrical wall socket. The Power LED on the front of the Cable Modem should light up and remain on.

5. Contact your Cable Internet Service Provider to activate your account. Usually, your Cable Internet Service Provider will need what is called a MAC Address for your Cable Modem in order to set up your account. The MAC address is printed on a bar code label on the bottom of the Cable Modem. Once you have given them this number, your Cable Internet Service Provider should be able to activate your account.

The Hardware Installation is now complete.

Your Cable Modem is ready to use.

Power (Green) When this LED is on, it indi-

cates that the Cable Modem is correctly supplied with power. The LED should remain lighted constantly.

Activity (Green) When this LED is on, it indi-

cates that the Cable Modem is properly connected to your PC or other Ethernet device, either through the USB or Ethernet Port on the back of the Cable Modem. The LED flashes when data is being transmitted to or from your PC (or other Ethernet device) through the Cable Modem.

Cable (Green) This LED will blink to indicate

that data is being transmitted to or from your Cable Modem to the Internet connection.

Status (Green) This LED will go through a

series of flashes as the Cable Modem goes through its start up process. Once the process is complete, the LED will remain lighted to show a successful connection to your Internet Service Provider. The Cable Modem will go through this process every time power is taken away from and restored to the it, or when the Reset button is pressed. This process can be fairly quick or prolonged, depending on your Provider, Inter net traffic in your area, etc. If this LED is still blinking 10 minutes after the Cable Modem has been powered up or reset, it is an indication of a connection problem. Recheck your physical connections and call your ISP for more information.
