The system ID PROM, sometimes referred to as the SCC, provides the server module with the host ID, MAC addresses, and some Oracle ILOM configuration information.
The system ID PROM does not typically require replacement. However, if you replace the ID PROM, be aware that the host ID and MAC address will change.
When you replace the enclosure assembly, swap the system ID PROM from the original enclosure assembly to the replacement enclosure assembly. This action ensures that your server module will maintain the same host ID and MAC address.
