After you finish
• Each processor socket must always contain a cover or a PHM. Protect empty processor sockets with a
cover or install a new PHM.
• If you are removing the PHM as part of a system board replacement, set the PHM aside.
• If you are reusing the processor or heat sink, separate the processor from its retainer. See
processor from carrier and heat sink" on page 211
• If you are instructed to return the defective component, please package the part to prevent any shipping
damage. Reuse the packaging the new part arrived in and follow all packaging instructions.

Separate the processor from carrier and heat sink
This task has instructions for separating a processor and its carrier from an assembled processor and heat
sink, known as a processor-heat-sink module (PHM). This procedure must be executed by a trained
technician.
About this task
Attention:
• Go over "Installation Guidelines" on page 137
• Turn off the server and peripheral devices and disconnect the power cords and all external cables (see
"Power off the server" on page
• 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.
• 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.
• Do not allow the thermal grease on the processor or heat sink to come in contact with anything. Contact
with any surface can compromise the thermal grease, rendering it ineffective. Thermal grease can damage
components, such as the electrical connectors in the processor socket.
Note: The heat sink, processor, and processor carrier for your system might be different than those shown
in the illustrations.
