This chapter describes the functions of the cable modem’s LEDs and connectors.

When the PWR, SYNC, and READY LEDs are lit, the cable modem is working properly. The USB or ENET LED should also be lit depending on what port is being used.

The following provides an overview of the LED indicator lights on the front of the cable modem and what the LEDs mean.

•send: Indicates that data is being transmitted from the cable modem to the cable network.

•recv: Indicates that data is being received from the cable network.

•sync: Indicates the connection status between the cable modem and the cable network. The LED is lit when the cable modem has established a downstream channel with the cable service provider’s Cable Modem Termination System (CMTS).
