Troubleshooting
This chapter gives information about troubleshooting your Model DM602 ADSL Modem. After
each problem description, instructions are provided to help you diagnose and solve the problem.
Basic Functioning
After you turn on power to the modem, the following sequence of events should occur:
1. When power is first applied, verify that the Power LED is on.
2. After approximately 10 seconds, verify that 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 modem is turned on:
• Make sure that the power cord is properly connected to your modem and that the power supply
adapter is properly connected to a functioning power outlet.
• Check that you are using the 15 V AC power adapter supplied by NETGEAR for this product.
If the error persists, you have a hardware problem and should contact technical support.
