Front Panel Description

The front panel of your cable modem provides LED status indicators 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 ONLINE LED status

indicators illuminate continuously to show that the cable modem is active and fully

operational. See Front Panel LED Status Indicator Functions (on page

32) for more

information on front panel LED status indicator functions.
