• Each processor socket must always contain a cover or a PHM. When removing or installing a PHM,
protect 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 processor board supports multiple processors, install
the PHMs starting with the first processor socket.
Note: The heat sink, processor, and processor carrier for your system might be different from those shown
in the illustrations.
The following illustration shows the components of the PHM.
