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.
• If the server is in a rack, remove it from the rack.
• 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
