Investigating Software Configuration Problems

Software problems usually occur when your software configuration contains incomplete or incorrect information.

Connection to Device Fails During Software Configuration

•For a LAN connection, verify that the IP address matches the IP address previously stored into the configuration of the router. You must have previously (through QuickSET) set the Ethernet LAN IP address and Subnet Mask, enabled IP routing, saved the Ethernet configuration changes and rebooted the router for the new IP address to take effect.

•Check that your LAN cable is wired correctly and each end securely plugged in.

•Make sure that an IP route exists between your local PC and the CSX200. The PC and CSX200 must be on the same IP subnetwork or the CSX200 must be reachable through a router on your LAN.

•Check Network TCP/IP properties under Windows 95 or Windows NT, as described in the Read Me First! document.

User Cannot Communicate with Remote Network Station

If Bridging,

•Check that the Bridging Default Destination is set.

•Check that bridging to/from the remote router is set on.

•Be sure to reboot if you have made any bridging destination or control changes.
