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—If a battery is included, this light 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.
