Operation Manual

Front Panel Description

The front panel of your cable modem provides status lights that indicate how well and at what state your cable

modem is operating. After the cable modem is successfully registered on the network, the POWER and CABLE

status indicators illuminate continuously to show that the cable modem is active and fully operational. See Front

Panel Status Indicator Functions, later in this guide, for more information on front panel status indicator
