Appendix B - Trouble Shooting
The following section gives details about troubleshooting issues for your NB1300Plus4 ADSL
Modem. Problems are divided into different areas to assist you in finding the appropriate
solution.
General Modem Operation
Before continuing, refer to the correct power up sequence to verify that your NB1300Plus4
ADSL Modem is operating.
Correct power up sequence
After you turn on your NB1300Plus4 ADSL Modem, the following sequence should occur:
1. When power is first applied, verify that both the Power LED and Ready LED are on.
2. The RDY LED will turn off after 5 seconds.
3. After approximately 10 seconds, verify that:
■
The RDY LED will flash which indicates that the modem is ready for use.
■
The LAN LED will only light when a ethernet cable is connected and a successful LAN
connection is made.
If any of these conditions does not occur, refer to the appropriate section below.
PWR LED Not On
If the PWR and other LEDs are off when your ADSL modem is turned on:
■
Make sure that the power cord is properly connected to your ADSL Modem and that the
power supply adapter is also properly connected to a functioning power outlet.
■
Check that you are using the 12 V AC power adapter supplied by NetComm for this
product.
If the error persists, you have a hardware problem and should contact NetComm technical
support.
Resetting the NB1300Plus4 ADSL Modem
To restore the factory default configuration settings without knowing the administration
password or IP address, you must use the Default Reset button on the rear panel of the ADSL
Modem.
1. Press and hold the Default Reset button for about 10 seconds.
2. Release the Default Reset button and wait for the Modem to reboot (which will take
approximately one minute).
3. Once the RDY and WAN LEDs are flashing, the unit has finished rebooting and the factory
defaults have been restored. Do not power off the modem or press reset again until these
LEDs are flashing.
