Troubleshooting 105
Problems with the factory configuration
•
Compare the router configuration with your router order.
Check the following items:
•
Either
ISDN BRI(S/T)
or
ISDN BRI(S/T and U)
should be
indicated in the
Interfaces detected
message during boot of the
router. One or two RJ45 ISDN ports are provided on the rear panel.
•
Verify that the model number is correct (displayed during the boot
procedure). The model number (and serial number) is also displayed on
the main window of Configuration Manager.
Investigating Software Configuration Problems
Problems connecting to the router
If you cannot connect your PC to the target router for configuration:
•
For a LAN connection, verify that the router’s IP address matches the IP
address previously stored into the router’s configuration.
You must have previously set the router’s Ethernet LAN IP address and
subnet mask, saved the Ethernet configuration changes, and rebooted the
router for the new IP address to take effect.
•
Check that your LAN cable is pinned correctly and each end securely
plugged in.
•
Make sure the PC and target router are on the same IP subnetwork or the
target router is reachable through a router on your LAN. They can,
however, be on different networks if IP routing is off.
•
Check Network TCP/IP properties under Windows 95 and the control
panel of the TCP/IP driver installed under Windows 3.1.
•
Check if the LAN LED on the router’s front panel blinks when 'pinged'.
•
Check your Ethernet board IRQ settings: the PC’s table may become
confused. If it is the case, reboot your PC.
