The server has a pair of dual-redundant SPs (SP0 and SP1) located in the front of the server. One SP functions as the Active SP to manage the server, while the other acts as a Standby SP that assumes the Active SP role in the event of a failure.
When you power on the system, the boot process begins under the control of the Oracle ILOM system console. The system console displays status and error messages generated by firmware-based tests that run during the system startup.
Note - To see these status and error messages, connect a terminal or terminal emulator to the SER MGT ports on the two SPs prior to applying power to the server.
After the system console finishes its low-level system diagnostics, the Active SP initializes and runs a suite of higher level diagnostics. When you access the SP using a terminal device connected to the Active SP SER MGT port, you see the diagnostic and startup messages.
For a detailed discussion on configuring the system console, refer to the Server Administration, and the Oracle ILOM documentation.
