Apply factory software service within an HPE Cluster Platform configuration carrying the 66-129 designation. HB484A1 identifies that service scope as factory software work rather than a physical cluster component. It is not a server, storage device, network switch, cable, or rack accessory. Retaining the complete 66-129 designation matters because it distinguishes this service scope from other Cluster Platform work. Factory software service places the applicable software activity in the factory stage of the Cluster Platform configuration. This SKU applies where the technical requirement specifically calls for factory software service and the associated Cluster Platform scope is 66-129. Its defining characteristic is the named factory-service treatment, not a hardware port count, compute capacity, storage capacity, or device form factor. Associate the service with the applicable platform configuration rather than treating it as standalone hardware. Use the full HB484A1 code when matching the service to the intended HPE Cluster Platform configuration. The code and the 66-129 wording stay together to preserve the designated service scope. Factory handling differentiates this service from software work performed after equipment arrival. The 66-129 value is a service designation in this context, not a stated capacity, quantity, performance rating, or hardware specification.
