DI-206 ISDN Remote Router

Appendix A - Troubleshooting

This chapter contains some problems you may run into when using your router. After each problem description, we have provided some instructions to help you diagnose and solve the problem.

Some Common Problems With the DI-206

None of the LEDs are on when you power up the router

Check the power cord and the power supply and make sure it is properly connected to your DI-206. If the error persists you may have a hardware problem. In this case you should contact technical support.

Connecting the RS-232 cable, cannot access the console program

Check to see if the DI-206 is connected to your computer’s serial port.

Check to see if the communications program is configured correctly. The communications software should be configured as follows:

VT100 terminal emulation.

9600 Baud rate.

No parity, 8 Data bits, 1 Stop bit.

Problems With the ISDN Line

If you are having problems making a connection through the ISDN line, try performing a Loopback Test (in the console program choose System Maintenance, Diagnostic, Loopback Test). If the loopback test succeeds then your physical connection to your phone company is ok and the problem probably lies in your ISDN settings (located in the console program under Interface Configuration, ISDN). Alternatively, the problem could be with the router or computer you are trying to call.

Problems with the LAN Interface

Can’t PING any station on the LAN

1.Check the LAN LED on the front panel of your router. If it is on, then the link is up. If it is off, then check the cables connecting the router to your LAN.

2.Make sure the LAN is enabled in the Interface Configuration, LAN submenu of the console program.
