1.The blue Power LED remains off.
Verify that the wall transformer is plugged into an electrical outlet and that the connection to the modem is secure.
Confirm the modem is plugged into a “live” electrical outlet. Make sure no light switch controls the plug and has been inad- vertently turned off. It is not a recommended configuration to have the modem plugged into an electrical outlet that is con- trolled by a light switch.
2.The Status LED continues to stay red.
This indicates one of two possible problems. If the modem was just upgraded, this indicates a problem with the new software. If the modem is new, this indicates a factory defect in the hard- ware. In both cases, try power cycling the modem by unplugging the modem and plugging it back in.
If the problem was due to the new software, the old image will now run and the modem should come up. Verify the desired image is running by checking the Upgrade Software screen.
If after power cycling the Status LED remains red, contact
Customer Support.
3.The DSL Link LED never starts blinking.
The modem does not detect another modem on the other end of the DSL line.
The DSL line is not plugged in or the DSL line is not properly connected to the “remote” end. Verify the cable is properly connected at both ends.
