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-308
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-308. 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-308 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 okay and the problem probably lies in your
ISDN settings (located in the console program under Interface Configuration,
ISDN submenu). 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.
