LED Identification
The DOXport 1110 modem has six front panel lights called LEDs (Light-Emitting Diodes).
The LEDs let you monitor status during installation and operation.
See Table 2 for a description of the six LEDs.
LED Acquisition States
When power is applied to the cable modem, the power LED turns solid green, indicating the
start or the acquisition process. The process will continue after the cable modem has
established a connection to the cable TV network. No additional intervention is required on
your part. The modem automatically acquires to and registers with the cable data network.
