Ethernet (LAN) Communication Problems

•

IP Address not set correctly in FastSwitch.

•

Cables not installed.

•

Default Route not set when router exists.

1. Connect a VT100-compatible terminal to the CTRL port to check the IP Address and mask in

the FastSwitch and ensure the values is correct.

2. Perform ping to determine whether the FastSwitch is communicating on the network.

WEB Communication Problems

•

Browser not configured for accessing FastSwitch.

•

Eight web management sessions already in progress.

1. At your browser, ensure that cookies are enabled, and that Java code is supported and enabled.

2. Ensure that your user name and password have been entered correctly.

3. Check that FastSwitch has been configured with HTTP enabled.
