Description: A Field Replaceable Unit (FRU), is defined as a hardware component which is designed to be separately removable for replacement or repair. For the purposes of this definition, a motherboard and a fixed hard disk are FRUs, whereas a fixed hard disk platter or a chip fixed in place on the motherboard are not FRUs since they are not designed to be separately removable. Each instance within the FRU table should contain the device group and instance data for the associated hardware component.
