Familiarizing Yourself with Your Cable Modem Your Zoom cable modem has several LED light indicators on its front panel, so you can monitor its operation and perform troubleshooting if necessary. The following table defines these lights and explains how to interpret them. This table is for reference only and is not required for cable modem installation. LIGHT NAME MODE STATUS READY Lit Power is on. SYNC Blinking Fast Searching for “data” channel from the cable provider.
When you connect your cable modem, all connections will originate from this back panel. Continue with Chapter 1 (page 8) for installation instructions. If you would like to use your cable modem with multiple computers, you can do so by adding a hub, router, or gateway. Zoom offers gateway/routers that work with your cable modem. You will also have to contact your cable service provider.
1 Installing Your Cable Modem Note: If your cable company provides you with an installation procedure, follow it instead of the instructions in this chapter. This chapter describes how to connect your Zoom cable modem to a computer and to your cable service. Installation consists of a few simple steps: 1. Install any software required. 2. Make the physical connections to your cable modem. 3. Provide your cable provider with the proper MAC addresses (if necessary).

The Setup Wizard continues the software installation process.
Making the Connections Connecting your cable modem is simple. Typical connections are shown below. Coaxial Cable Power Adapter Ethernet Cable Tips: ✔ If you are using the mounting stand and find that the modem is top heavy with the coaxial cable connection on top, turn the modem over so that the coaxial cable connection is on the bottom. ✔ Your service provider may advise you that a splitter, amplifier, and high-pass filter are required.
CAUTION: Place the modem so that there is one inch of free space between its top and sides and any other device or the wall. Do not block the vents in any way. Failure to allow proper air circulation can result in serious damage to the modem. Do not place any items on top of the modem while it is on. Do not place the modem near a heating or air conditioning duct, in direct sunlight, or anywhere susceptible to drastic temperature changes.

The modem starts an automated power-up process that is described on page 14.
The Modem’s Power-Up Process As your cable modem powers itself up, the lights on the front panel indicate the different stages. When the modem initially powers itself up, the PWR light comes on. After completing a self-test, the cable modem registers with the cable system. While the modem is searching for and registering with the cable system, the SYNC light blinks: At first the light blinks fast; then it blinks slowly. After the process is complete, the SYNC light stays on steady.
