IBM BladeCenter T Type 8720 - Manual (Page 77)

Chapter 5. Service replaceable units
This chapter describes the removal of server components.
Important: The field replaceable unit (FRU) procedures are intended for trained
servicers who are familiar with IBM xSeries products. See the parts
listing in Chapter 7, “Parts listing, BladeCenter T Type 8720 and
8730,” on page 107 to determine if the component being replaced is a
customer replaceable unit (CRU) or a FRU.
As further guidance, the components in the BladeCenter T server have
an alphabetical stamp in the metal that identifies the order they were
assembled at the factory (for example, a, b, c, etc.).
