What is chassisFruNumber?

This OCTET STRING is the Field Replaceable Unit (FRU) number assigned to the chassis, the catalog code used to order an identical replacement part. An admin hands this exact FRU number to procurement or to the vendor's parts desk so the replacement shipped back is guaranteed to be the correct interchangeable part. For example, when a chassis midplane needs replacing, the technician quotes chassisFruNumber to the parts desk to receive the exact interchangeable frame rather than a similar but incompatible model.
