Troubleshooting
This chapter gives information about troubleshooting your Model DG814 DSL Modem Internet
Gateway. After each problem description, instructions are provided to help you diagnose and solve
the problem.
Basic Functioning
After you turn on power to the gateway, the following sequence of events should occur:
1. When power is first applied, verify that the Power LED is on.
2. Verify that the Test LED lights within a few seconds, indicating that the self-test
procedure is running.
3. After approximately 10 seconds, verify that:
a. The Test LED is not lit.
b. The LAN port LEDs are lit for any local ports that are connected.
If a port’s LED is lit, a link has been established to the connected device. If a LAN port is
connected to a 100 Mbps device, verify that the port’s LED is green. If the port is 10
Mbps, the LED will be amber.
If any of these conditions does not occur, refer to the appropriate following section.
PWR LED Not On
If the PWR and other LEDs are off when your gateway is turned on:
• Make sure that the power cord is properly connected to your gateway and that the power
supply adapter is properly connected to a functioning power outlet.
