2.4.4 BMC IP Address and external connection
The BMC IP address for a particular embedded NIC is always different from the IP address of the
Server’s operating system.
The BMC supports static and DHCP sourced IP address assignment on all of its management NICs. The
IP address source parameter must be set to “static” before the IP address, subnet mask, or gateway
address can be manually set.
