Assigning Switch Information
Note
Stack members retain their IP address when you remove them from a switch stack. To avoid a conflict
by having two devices with the same IP address in your network, change the IP address of the switch
that you removed from the switch stack.

If you are using DHCP, do not respond to any of the questions in the setup program until the switch

Understanding DHCP-Based Autoconfiguration
DHCP provides configuration information to Internet hosts and internetworking devices. This protocol
consists of two components: one for delivering configuration parameters from a DHCP server to a device
and a mechanism for allocating network addresses to devices. DHCP is built on a client-server model,
in which designated DHCP servers allocate network addresses and deliver configuration parameters to
dynamically configured devices. The switch can act as both a DHCP client and a DHCP server.
