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.  

 

1  POWER—Illuminates solid green to indicate that power is 

being applied to the cable modem 

2  DS (Downstream)—Illuminates solid green to indicate that the 

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. 

4  ONLINE—Illuminates solid green when the cable modem is 

registered on the network and fully operational 

5  LINK—Off when no Ethernet/USB device is present, 

illuminates solid green to indicate that an Ethernet/USB device 
is connected, and blinks to indicate that Ethernet/USB data is 
being transferred between the PC and the cable modem 

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.
