Note: If DHCP/Bootp is used to configure the switch, see the Note , above.
■ 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.

inbound telnet access only to a device having an authorized IP address.
For more information on IP Authorized managers, see “Enhancing Secu-
rity By Configuring Authorized IP Managers” on page “Using IP Autho-
rized Managers” on page 30.
