After the system console finishes its low-level system diagnostics, the ILOM service processor initializes and runs a higher level of diagnostics. When you access the ILOM service processor using a device connected to the serial management port, you see the output of the ILOM diagnostics.
By default, the service processor configures the network management port automatically, retrieving network configuration settings using the Dynamic Host Configuration Protocol (DHCP) and allowing connections using Secure Shell (SSH).
Note - If you are unable to use DHCP on your network, you must connect to the ILOM service processor using the serial management port to configure the network management port for your network. See Configure the Service Processor Network Management Port.
