Front Panel Description
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.

being applied to the cable modem

cable modem is locked onto the downstream signal or blinks to
indicate that the cable modem is scanning for the downstream
signal
3 US (Upstream)—Illuminates solid green to indicate the
upstream connection is operational, blinks to indicate that
upstream calibration is in progress and during registration with
the system. Off when the modem is off-line.

registered on the network and fully operational
5 LINK—Off when no Ethernet/USB device is present,

Note: After the cable modem is successfully registered on the
network, the POWER (LED 1), DS (LED 2), US (LED 3), and
ONLINE (LED 4) indicators illuminate continuously to indicate
that the cable modem is online and fully operational.
