BATTERY (optional model only)
—ON indicates the battery is charged. Blinking
indicates the battery charge is low. OFF indicates the unit is operating from
battery power, the battery charge is depleted, or the battery is defective or
missing
Notes:
After the residential gateway is successfully registered on the network, the
POWER, DS, US, and ONLINE LEDs illuminate continuously to indicate that the
residential gateway is active and fully operational.
The high-speed data operation is disabled when operating on battery power;
only the telephone service (if available on this model) is active when operating
on battery power.
LEDs may behave differently when the residential gateway 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 LED blinks to indicate that the unit is
operating under battery power.
The residential gateway 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.
