Activating the Cable Modem

Initialization Mode

After you install the cable modem and turn it on for the first time (and each time the modem is
reconnected to the power), it goes through five 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.
Note: All indicators flash once prior to the initialization sequence.
