A field replaceable unit is a component of a larger product or system that by design can be removed, ordered and replaced by a user or technician in the field (ie, without sending the entire product back to the original company, vendor or factory). An FRU can be a single part, a kit, or a complete assembly. Some IBM and family companies make use of FRU part numbers to identify such components. An entire IBM and family keyboard can have an FRU part number and it can be the same or different to the keyboard's regular (manufacturing) part number.
