The service processor plugs into a socket on the motherboard in the space between riser 2 and the right side of the chassis, as viewed from the rear. This is the riser that contains PCIe slots 2 and 5.
If the service processor is replaced, the configuration settings maintained in the service processor will need to be restored. Before replacing the service processor, you should save the configuration using the Oracle ILOM backup utility.
System firmware consists of both SP and host components. The SP component is located on the service processor and the host component is located on the CPU. These two components must be compatible. When the service processor is replaced, the SP firmware component on the new service processor may be incompatible with the existing host firmware component. In this case, the system firmware must be loaded as described in Install the Service Processor.
