Servicing the Motherboard
The motherboard includes two CMPs, NVMe connections, power distribution, memory control
subsystems, and all SPM (Oracle ILOM) logic. The motherboard hosts a removable SCC
PROM, which contains all MAC addresses, host ID, and Oracle ILOM configuration data.
Follow these procedures to remove and install the motherboard.
Caution - The motherboard should be serviced only by an Oracle qualified service technician.
Caution - Ensure that all power is removed from the server before removing or installing the
motherboard. You must disconnect the power cables before performing these procedures.
Caution - These procedures require that you handle components that are sensitive to
electrostatic discharge. This sensitivity can cause the components to fail. To avoid damage,
ensure that you follow antistatic practices to “Prevent ESD Damage” on page 41.
