What is a CRU? How is it different from a FRU?
A CRU is a Customer Replaceable Unit. A FRU is a Field Replaceable Unit. The difference being that FRUs are typically replaced by Sun authorized and trained personnel, and a CRU is a hardware part replaced by the customer themselves. FRUs and CRUs are easily identified throughout the Sun System Handbook version available to customers with a Sun Service Plan. FRUs are marked with [F] and CRUs are marked with [C]. Please see this page for more information about CRUs. http://www.sun.com/service/support/warranty/index.html#sunsresponse .
