N OTE : The switch will also broadcast a request for IP configuration settings
on each power reset.
N OTE : When using DHCP, you may lose the management connection if the
IP address assigned by the DHCP server has changed. To resolve this kind
of problem, ask your network administrator to configure a static binding for
your switch’s MAC address on the DHCP server.
Renewing DHCP – DHCP may lease addresses to clients indefinitely or for
a specific period of time. If the address expires or the switch is moved to
another network segment, you will lose management access to the switch.
In this case, you can reboot the switch to restore the default static
address.
If the address assigned by DHCP is no longer functioning, you will not be
able to renew the IP settings via the web interface. You can only restart
DHCP service via the web interface if the current address is still available.
