• 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.
• To ensure the best performance, check the manufacturing date on the new heat sink and make sure it
does not exceed 2 years. Otherwise, wipe off the existing thermal grease and apply the new grease onto it
for optimal thermal performance.
Notes:
• The heat sink, processor, and processor carrier for the system might be different from those shown in the
illustrations.
• PHMs are keyed for the socket where they can be installed and for their orientation in the socket.
• See https://serverproven.lenovo.com

• Before you install a new PHM or replacement processor, update your system firmware to the latest level.
