The motherboard assembly must be removed in order to access the following components:
Power supply backplane
Power distribution board
Note - The server must be removed from the rack for this procedure.
Caution - The server is heavy. Two people are required to remove it from the rack.
If you replace the motherboard, remove and transfer the service processor and System Configuration PROM from the old board to the new. This will preserve system-specific information that is stored on these modules.The SP contains system configuration data used by Oracle ILOM and the System Configuration PROM contains the system host ID and MAC address.
System firmware consists of both service processor and host components. The service processor component is located on the SP and the host component is located on the CPU. These two components must be compatible. When the motherboard is replaced, the host firmware component on the new motherboard may be incompatible with the SP firmware component on the service processor that was transferred to the new motherboard. In this case, the system firmware must be loaded as described in Install the Motherboard Assembly.
