CHAPTER 1: CONNECTIONS AND SETUP
Turning on the Cable Modem
After installing the Cable Modem and turn it on for the first time (and each time the modem is
reconnected to the power), it goes through several steps before it can be used. Each of these steps is
represented by a different pattern of flashing lights on the front of the modem.
If there is no lighted LEDs on the front panel, check the power adapter plug-in the power jack and
connect to CM correctly.
Note: All indicators flash once before the initialization sequence.
If both DS and US LEDs are flashing, it means the Cable Modem is automatically updating its system
software. Please wait for the lights to stop flashing. Do not remove the power supply or reset the Cable
Modem during this process.

General Troubleshooting
You can correct most problems you have with your product by consulting the troubleshooting list that
follows.
I can’t access the internet.
Check all of the connections to your Cable Modem.
Your Ethernet card may not be working. Check each product’s documentation for more information.
The Network Properties of your operating system may not be installed correctly or the settings may
be incorrect. Check with your ISP or cable company.
I can’t get the modem to establish an Ethernet connec tion.
Even new computers don’t always have Ethernet capabilities – be sure to verify that your computer
has a properly installed Ethernet card and the driver software to support it.
Check to see that you are using the right type of Ethernet cable.
The modem won’t register a cable connection.
If the modem is in Initialization Mode, the INTERNET light will be flashing. Call your Cable
Company if it has not completed this 5-step process within 30 minutes, and note which step it is
getting stuck on.
The modem should work with a standard RG-6 coaxial cable, but if you’re using a cable other than
the one your Cable Company recommends, or if the terminal connections are loose, it may not work.
Check with your Cable Company to determine whether you’re using the correct cable.
If you subscribe to video service over cable, the cable signal may not be reaching the modem.
Confirm that good quality cable television pictures are available to the coaxial connector you are
using by connecting a television to it. If your cable outlet is “dead”, call your Cable Company.
Verify that the Cable Modem service is Euro-DOCSIS compliant by calling your cable provider.
