interfaces you intend to use.
3. At the command prompt, type show ip-route to check that you have a path for the
destination IP to route to the interface.
4. Perform ping to determine whether the SC-IP is communicating on the network.
5. If ping was not successful, make sure that the link connection is established.
WEB Communication Problems

Browser not configured for accessing SC-IP.
•
Eight web management sessions already in progress.
•
Java 1.1 not supported or enabled on your browser.
1. At your browser, ensure that cookies are enabled, and that Java code is supported and enabled.
