ƒ On - When a single device is connected to either the Ethernet or the USB

 

 

port and no data is being sent to or from the modem.

 

 

ƒ Blinks - When only one Ethernet or USB device is connected and data is

 

 

being transferred between the consumer premise equipment (CPE) and

 

 

the cable modem.

ports.

 

 

Note: With both Ethernet and USB devices connected to the modem at the

 

 

same time, when data is transferred through only one of the devices

 

 

(Ethernet or USB), the LED illuminates continuously. Whenever data is sent

 

 

through both data ports (Ethernet and USB), the LED blinks as described

 

 

above.
