Important: The field replaceable unit (FRU) procedures are intended for trained
servicers who are familiar with IBM xSeries products. Customer
replacement units (CRUs) can be replaced by the customer. See the
parts listing in “System” on page 100 to determine if the component
being replaced is a CRU or a FRU.
