CRU and FRU List
The following is a list of customer-replaceable units (CRUs) and field-replaceable units (FRUs)
for the Sun Fire X2270 M2 Server. CRU and FRU designations refer to serviceability. For
reasons of safety and complexity, a component designated as a FRU must be serviced by an
Oracle Service Technician. A component designated as a CRU has safety and complexity levels
deemed to be sufficiently within the scope of a non-service personnel. However, if you feel that
servicing a component designated as a CRU exceeds your service capabilities, please contact
Oracle Service.
