Introduction 
 
Front Panel LED Status Indicator Functions 
Initial Power Up, Calibration, and Registration (AC Power applied) 
The following chart illustrates the sequence of steps and the corresponding 
appearance of the cable modem front panel LED status indicators during power up, 
calibration, and registration on the network when AC power is applied to the cable 
modem. Use this chart to troubleshoot the power up, calibration, and registration 
process of your cable modem. 
Note: After the cable modem completes Step 7 (Registration Completed), the modem 
proceeds immediately to Normal Operations. See Normal Operations (AC Power 
applied).

* The ONLINE LED is on whenever a PC is connected to the modem, and it blinks to indicate that data is being transferred. If the 
modem is used to provide telephone service only and is not connected to a PC, the ONLINE LED is off.
