• If the server is installed in a rack, slide the server out on its rack slide rails to gain access to the top cover,
or remove the server from the rack. See "Remove the server from rack" on page 124.
• 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.
