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 29) for more
