Notes
:
•
After the cable modem is successfully registered on the network, the
POWER
(LED 1) and
CABLE
(LED 4) LEDs illuminate continuously to indicate that the
cable mode is active and fully operational.
•
LEDs may behave differently when the cable modem is running on battery power
(without AC power). Most LEDs are disabled if the unit is operating on battery
power. In this mode, the
POWER
and
CABLE
LEDs blink to indicate that the unit
is operating under battery power but AC power has failed.
