Front Panel Description

Note: After the cable modem is successfully registered on the network, the POWER (LED 1), DS (LED 2), US (LED 3), and ONLINE (LED 4) LEDs illuminate continuously to indicate that the cable mode is active and fully operational.

8BATTERY (optional)—Illuminates solid green to indicate that the battery is charged. Blinks to indicate that the battery charge is low. The LED is off when operating from battery power, when the battery charge is depleted, or the battery is defective

Notes:

For models equipped with battery backup, LEDs may behave differently when the cable modem is running on battery power. Most LEDs are disabled if the unit is operating on battery power. In this mode, the POWER LED blinks to indicate that the unit is operating under battery power.

The cable modem should only run on battery power when AC power has failed. If the POWER LED indicates that the unit is running on battery power but the AC power has not failed, verify that the power cord is plugged into a working AC outlet.

Many of the functions of the cable modem may be disabled when operating on battery power; only the telephone service will remain active.
