2.3.3 Field-Replaceable Units (FRUs)
Many of the library's major components are available separately as Field-Replaceable
Units (FRUs). Sometimes referred to as spare parts. These components can be re-
moved and replaced in the field by qualified personnel. See Chapter 7 for a complete
list of FRUs, their part numbers and removal/replacement instructions.
Some FRUs can be added to a unit as an expansion item. The instructions for in-
stalling an expansion FRU are contained in Chapter 7.
