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, Type 8839," on page 105 to determine whether a component being replaced is a customer replaceable unit (CRU) or a FRU. Microprocessor removal Note: v Read "Installation guidelines" on page 33. v Read the safety notices beginning on page 109. v Read "Handling electrostatic discharge-sensitive devices" on page 112. Complete the following steps to remove a microprocessor: 1. Shut down the operating system, turn off the blade server, and remove the blade server from the BladeCenter unit (see "Removing the blade server from the BladeCenter unit" on page 39). 2. Carefully lay the blade server on a flat, nonconductive surface. 3. Open the blade server cover (see "Opening the blade server cover" on page 40 for instructions). 4. Remove the bezel assembly (see "Removing the blade server bezel assembly" on page 42 for instructions). 5. Identify the microprocessor to be removed. Note: If you are replacing a failed microprocessor, make sure that you have selected the correct microprocessor for replacement (see "Light path diagnostics" on page 86). 6. Remove the air baffle. © Copyright IBM Corp. 2004 69
