About this task
Attention: 
•  Read “Installation Guidelines” on page 185 to ensure that you work safely.
•  Power off the server and disconnect all power cords for this task.
•  Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static- 
sensitive components in their static-protective packages until installation, and handling these devices with 
an electrostatic-discharge wrist strap or other grounding system.
•  Do not touch the processor contacts. Contaminants on the processor contacts, such as oil from your skin, 
can cause connection failures.
Note: The heat sink, processor, and processor carrier for your system might be different from those shown 
in the illustrations.
