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.

the cable modem
2 DS (Downstream)—Illuminates to indicate that the cable
modem is locked onto the downstream signal(s). The DS LED
blinks to indicate that the cable modem is scanning for the
downstream signal
3 US (Upstream)—Illuminates to indicate the upstream
connection is operational
4 ONLINE—Illuminates when the cable modem is 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.
