About this task
To avoid potential danger, make sure to read and follow the safety information.
Attention:
• Read "Installation Guidelines" on page 43
you work safely.
• To transfer Intel ® On Demand Suite from the defective processor to the new processor, read the PPIN of
the defective processor before powering off the system. For more information, see
Demand" on page 239.
• Each processor socket must always contain a cover or a PHM. When removing or installing a PHM,
protect the empty processor sockets with a cover.
• Do not touch the processor socket or processor contacts. Processor-socket contacts are very fragile and
easily damaged. 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.
• Remove and install only one PHM at a time. If the system supports multiple processors, install the PHMs
starting with the first processor socket.
Note: The heat sink, processor, and processor carrier for the node might look different from those shown in
the illustrations in this section.
The following illustration shows the components of the PHM.
