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 CSX400. The PC and CSX400
must be on the same IP subnetwork or the CSX400 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.
