Front Panel Status Indicator Functions

Initial Power Up, Calibration, and Registration

The following chart illustrates the sequence of steps and the corresponding appearance of the cable modem front panel status indicators during power up, calibration, and registration on the network. Use this chart to troubleshoot the power up, calibration, and registration process of your cable modem.

After the cable modem completes step 7 (Registration Completed), the modem proceeds immediately to step 8 (Normal Operations).

sent to or from the modem.

 

 

 

BLINKS - LED blinks when only one Ethernet or USB device is connected and

 

 

 

data is being transferrd between the consumer premise equipment (CPE) and the cable modem.

 

 

 

OFF - When no devices are connected to either the Ethernet or USB ports.

 

 

 

Note: With both Ethernet and USB devices connected to the modem at the same time, when data is being

 

 

 

transferred through only one of the devices (Ethernet or USB), the indicator will illuminate continuously.

 

 

 

Whenever data is being sent through both data ports (Ethernet and USB) simultaneously, the indicator

 

 

 

will blink as described above.
