Chapter 3 Operation of Front Panel Indicators

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 (Data Network Registration Complete), the cable modem proceeds immediately to Normal Operations. See Normal Operations (AC Power applied) (on page 24).
