1POWER—Illuminates solid green to indicate that AC power is being applied to the cable modem. AC power must be available to recharge the battery.

2RECEIVE DATA—Blinks to indicate that the cable modem is receiving data from the cable network

3SEND DATA— Blinks to indicate that the cable modem is sending data to the cable network

4CABLE—Illuminates solid green when the cable modem is registered on the network and fully operational. This indicator blinks to indicate one of the following conditions:

•The cable modem is booting up and not ready for data

•The cable modem is scanning the network and attempting to register

•The cable modem has lost registration on the network and will continue blinking until it registers again

5PC—Illuminates solid green to indicate that an Ethernet/USB carrier is present and blinks to indicate that Ethernet/USB data is being transferred between the PC and the cable modem

6LINE 1—Illuminates solid green when telephone line 1 is in use

7LINE 2—Illuminates solid green when telephone line 2 is in use

8LOW BATTERY—Illuminates to indicate that approximately 20 percent of charge is remaining in the battery.

9REPLACE BATTERY—Illuminates to indicate that the battery could not be fully charged. While the battery may be able to provide some backup power, it should be replaced to restore maximum capacity.

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.
