This section is designed to assist in troubleshooting the XL-12000B. It also describes how to reach Technical Support at Tut Systems. Tut Systems takes pride in its products and would be more than happy to help with problems associated with the XL-12000B. Please take a moment and review the following answers to commonly asked questions before calling Technical Support.

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 inadvertently turned off. It is not a recommended configuration to have the modem plugged into an electrical outlet that is controlled by a light switch.

2.The Status LED continues to stay red and the DSL link LED is not blinking.

Try power cycling the modem by unplugging the modem and plugging it back in.

If after power cycling the Status LED remains red, contact

Customer Support.

3.The DSL Link LED never starts blinking.

The DSL line is not plugged in or the DSL line is not properly connected to the “remote” end. Verify that the cable is properly connected at both ends.

Both modems have the same setting on the Master/Slave switch. Verify by checking both modems’ Master/Slave switch on the front panel. Make sure that one of the modems is a Master and the other is a Slave. Check all patch cables to be sure the pinout is correct and connections are well seated.
