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 "System" on page 162 to determine if the component being replaced is a customer replaceable unit (CRU) or a FRU. Thermal grease This section contains information about removing and replacing the thermal grease between the heat sink and the microprocessor. The thermal grease must be replaced anytime the heat sink has been removed from the top of the microprocessor and is going to be reused, or when debris is found in the grease. Note: v Read "Installation guidelines" on page 45. v Read the safety notices at "Safety information" on page 169. v Read "Handling electrostatic discharge-sensitive devices" on page 172. Complete the following steps to replace damaged or contaminated thermal grease on the microprocessor and heat sink: 1. Place the heat sink on a clean work surface. 2. Remove the cleaning pad from its package and unfold it completely. 3. Use the cleaning pad to wipe the thermal grease from the bottom of the heat sink. Note: Be sure that all of the thermal grease is removed. 4. Use a clean area of the cleaning pad to wipe the thermal grease from the microprocessor; then, dispose of the cleaning pad after all of the thermal grease is removed.
