Powering Options

Description
The cable modem can operate from standard AC power or from battery power when
there is a loss of AC power. After a cable modem powers on, it performs an internal
self test to ensure proper initialization of the cable modem. When the self-test is
complete, the cable modem will begin normal operation if AC power is available. If
the cable modem is operating from battery power, it will begin operation in Power
Saving Mode or in Normal Operating mode depending on how the cable modem has
been configured by the service provider. AC power must be available in order to
charge the battery.
The following table illustrates the status of the front panel LED status indicators
when the no power condition exists.
