Removing a microprocessor Attention: v Do not allow the thermal grease on the microprocessor and heat sink to come in contact with anything. Contact with any surface can compromise the thermal grease and the microprocessor socket. v Handle the microprocessor carefully. Dropping the microprocessor during installation or removal can damage the contacts. v Do not touch the microprocessor contacts; handle the microprocessor by the edges only. Contaminants on the microprocessor contacts, such as oil from your skin, can cause connection failures between the contacts and the socket. Chapter 3. Removing and replacing server components 87
