Troubleshooting; Basic Functioning - NETGEAR RT338 Reference Manual

This chapter gives information about troubleshooting your Model RT338 ISDN Router. After each
problem description, instructions are provided to help you diagnose and solve the problem.

Basic Functioning

After you turn on power to the router, the following sequence of events occurs:
• The PWR LED lights.
• The TEST LED blinks at a rate of 0.5 Hz for about one minute, after which it turns off.
The router performs a self-test for 30 seconds during the time the TEST LED is blinking.
The self-test includes briefly lighting all the ISDN LEDs.
• If the Ethernet connection is correctly made, the LAN Link LED should be lit.
• If your router has been configured, the ISDN D LED should light within the first two minutes
of operation.
If any of these conditions does not occur, refer to the appropriate following section.
PWR LED
If the PWR LED and other LEDs are off when your router is turned on:
• Make sure that the power cord is properly connected to your router and that the power supply
adapter is properly connected to a functioning power outlet.
• Verify that you are using the 12 V DC power adapter supplied by NETGEAR for this product.
If the error persists, you have a hardware problem and should contact technical support.
