Install the SFPs from the original controller in the host ports on the new controller, if they were
installed in the original controller, and reconnect all the cables.
If you are using more than one host protocol, be sure to install the SFPs in the correct host
ports.
4. If the original controller used DHCP for the IP address, locate the MAC address on the label on
the back of the replacement controller. Ask your network administrator to associate the DNS/
network and IP address for the controller you removed with the MAC address for the
replacement controller.
Note: If the original controller did not use DHCP for the IP address, the new controller
adopts the IP address of the controller you removed.
