With the introduction of the Dell R660xs, the server FRU model paradigm changes from the Dell R640. The Dell R660xs server FRU is a complete server replacement for Profiles A1, A2, A3 and contains all necessary components. Profile A31 has the same server FRU code as A3 but WILL require moving two HDDs from the failed A31 server.
