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 products. See the parts listing in Chapter 7, “Parts listing, BladeCenter Type 8677 and 1881,” on page 79 to determine if the component being replaced is a customer replaceable unit (CRU) or a FRU.
Note: Blade modules (I/O, management, power), servers, and blowers must be replaced during service within two minutes.
