1 Getting Started Before you install your cable modem, you must have cable modem service with a cable company. Information for Cable Service Provider You must provide your cable service provider with the information summarized below, which is located on the bottom of your modem.
Package Contents Your package contains the following items: • Cable modem • Ethernet cable • USB cable • Power cube • Software CD-ROM. The CD contains the installation software, documentation, warranty, and Customer Support information. If anything is missing or damaged, contact Zoom Customer Support or whoever sold you the modem. You Will Also Need • Any one of the following to connect to the modem: ! A Windows, Macintosh, or Linux computer with an Ethernet port.
2 Installing Your Cable Modem This chapter describes how to install your cable modem. • To connect the cable modem to a router, skip to page 7. • If you have to connect the cable modem to your Windows computer’s USB port, go to Installing the Software on page 9. • Most users will connect the cable modem to a computer’s Ethernet port. To do that, follow the steps below. Connecting Your Cable Modem to a Computer’s Ethernet Port 1 Shut down the computer that you are going to connect to the cable modem.
3 Connect the modem to the cable outlet. ! If you have a wall outlet cable jack: Connect one end of the coaxial cable to the modem’s CABLE connector and connect the other end to the wall jack. ! If you do not have a wall jack: You should have coaxial cable entering your house close to where you want to locate your cable modem. Connect the end of this cable to the modem’s CABLE connector. 4 Plug the included power cube into a power strip or wall outlet and then into the modem’s POWER jack.
Connecting Your Cable Modem to a Router 1 The router should not be plugged in or powered up. If it is, unplug it. 2 Plug one end of the Ethernet cable into the modem’s LAN jack and the other end into the router’s WAN Ethernet jack, typically labeled WAN or Internet. Tip: The modem has a fold-out base, so you can stand it upright or lie it flat, depending on your preference. 3 Connect the modem to the cable outlet.
5 Power-up the router. Wait for the router to complete its power-up sequence. The modem’s LINK light comes on. 6 You may need to restart some or all of the computers attached to the router. 7 At this point, the equipment at your cable company will communicate with your modem to finalize the installation. You should follow any directions that your cable provider has given to you. In some cases, everything will happen automatically.
Installing the Software—USB Users Only Important! This section is only for Windows computer users who need to use the cable modem’s USB port. Windows computer users who are using the USB option MUST install the software BEFORE installing the hardware. Note, however, that you must remove any existing USB modem drivers on your Windows computer before beginning this software installation.
6 Close any applications that may be open, then remove the CD from the CD-ROM drive. 7 Shut down the computer. Congratulations! You have installed the software. Continue with the next section, Installing the Hardware—USB Users Only. Installing the Hardware—USB Users Only 1 Shut down the computer that you are going to connect to the cable modem. 2 Plug one end of the USB cable into the modem’s USB port and the other end into your computer’s USB port.
4 Plug the included power cube into a power strip or wall outlet and then into the modem’s POWER jack. The modem performs an automated power-up process and registers with the cable system. When the process is complete, all the front panel lights will stay on steady. (The table on page 15 lists the lights and their modes.) Note: It may take several minutes for the modem to register with the cable system.
Completing the Installation Please observe the following suggestions: • Do not block the modem vents in any way. Failure to allow proper air circulation can result in serious damage to the modem. Place the modem so that there is one inch of free space between its top and sides and any other device and the wall. • Do not place any items on top of the modem while it is plugged in.
3 Using Your Cable Modem Now that you have installed your Zoom cable modem and it has synchronized itself with the cable network, your cable modem is ready to connect to the Internet. To Connect to the Internet To connect to the Internet, use your Web browser. If you are a Windows user and cannot connect, your Web browser settings may need adjustment. Your Web browser should be set to use a network connection (this might be called a “Local Area Network” or “broadband” connection).
If You Unplug Your Cable Modem or Lose Power If you power down your cable modem, or if power is lost for any other reason, all communication between the modem and the cable system will be terminated. When power is restored, the modem will go through the full startup and synchronization process before you can connect to the Internet.

Your Zoom cable modem has several lights on its front panel to help you monitor the modem’s status. Light Name Mode Status POWER Solid Power is on.
Problem: Solution: I cannot access my Internet service or send or receive email.

Check to see that your cable TV is working. ! Press the recessed RESET button on the back of the cable modem by using a paperclip.
Problem: Solution: I have connected a router to the cable modem but now cannot access the Internet or send or receive email.

First try shutting down and restarting each computer connected to the router. Allow the modem time to resynchronize with the cable system.
Problem: I receive the on-screen message “Configure TCP/IP Failure Error.” Solution: First make sure that your Ethernet cable is plugged in, then unplug your modem from the electrical outlet for several seconds, and then plug it back in. Be aware it will take time for the modem to re-register itself and synchronize itself with the cable system. Problem: I receive the on-screen message “Undetected Network Adapter.” Solution: The Ethernet or USB adapter was not installed correctly.
