FRU (Field Replaceable Unit)

        A Field Replaceable Unit or FRU is a circuit board, part or assembly that can be quickly and easily removed from a personal computer or other piece of electronic equipment, and replaced by the user or a technician without having to send the entire product or system to a repair facility. FRUs allow a technician lacking in-depth product knowledge to fault isolate and replace faulty components.

       

        A typical desktop computer is composed almost entirely of FRUs, including:
