the system management port, you can access the Lenovo XClarity Controller directly by connecting your
laptop to the management port using an Ethernet cable. Make sure that you modify the IP settings on the
laptop so that it is on the same network as the server default settings. A dedicated management network
provides additional security by physically separating the management network traffic from the production
network.
