APPENDIX A. TROUBLESHOOTING

This appendix describes problems potentially encountered when using

Digital Networks WebView and presents suggested solutions for

correcting these problems.

Troubleshooting

Cannot Connect to the Switch

If you attempt to connect to the switch and the main window does not

appear, make sure that the correct IP address is entered in the URL field

of the browser.

•Check the network connections of both your workstation and the

switch.

•Try to Ping the IP address to see If it’s indeed reachable.

•Set the IP gateway if necessary.

•Make sure the correct password is entered.

•Make sure the HTTP Server parameter is set to “ENABLED.”

System is Disconnected from the Switch

If your workstation is disconnected from the switch during an active

session, you may see the following messages:

or, “Device is not responding to SNMP queries”

•Reconnect the workstation to the switch. You may need to re-enter

your latest changes, but the user interface should become available

again for use.

•If the user interface does not become available after reconnecting,

close the Digital Networks WebView window and start a new session.
