Operational Problems
•
The Self Test has failed
• Access is attempted from a different LAN segment, and the Default Gateway IP Address has not
been set up in the Cisco VG30D Voice Gateway unit
or
• A connection was made to the web server before the unit is fully operational. This may result in a
delay in displaying the main window and could also result in question marks appearing in the SCN
Status. You can resolve this by refreshing the page or by closing down and then restarting the
browser.
