can be verified by selecting:

also check the DHCP/Bootp server configuration to verify correct IP

■ If you are using DHCP to acquire the IP address for the switch, the IP
address “lease time” may have expired so that the IP address has changed.
For more information on how to “reserve” an IP address, refer to the
documentation for the DHCP application that you are using.
■ If one or more IP-Authorized managers are configured, the switch allows
web browser access only to a device having an authorized IP address. For
more information on IP Authorized managers, see Chapter 10, “Using
Authorized IP Managers for Increased Management Security”.
■ Java™ applets may not be running on the web browser. They are required
for the switch web browser interface to operate correctly. See the online
Help on your web browser for how to run the Java applets.
