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.
8 BATTERY (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.
