About this task
Attention:
• Read
“Installation Guidelines” on page 55 and “Safety inspection checklist” on page 56 to ensure that you
work safely.
• Power off the server and peripheral devices and disconnect the power cords and all external cables. See
“Power off the server” on page 73.
• 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.
