Attention:• Intel Xeon SP Gen 2 processors are supported on the system board with part number 01PE842. If you usethe system board with part number 01GV277, update your system firmware to the latest level beforeinstalling an Intel Xeon SP Gen 2 processor. Otherwise, the system cannot be powered on.• 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 andeasily damaged. Contaminants on the processor contacts, such as oil from your skin, can causeconnection failures.• Remove and install only one PHM at a time. If the system board supports multiple processors, install thePHMs starting with the first processor socket.• Do not allow the thermal grease on the processor or heat sink to come in contact with anything. Contactwith any surface can compromise the thermal grease, rendering it ineffective. Thermal grease can damagecomponents, such as electrical connectors in the processor socket. Do not remove the grease cover froma heat sink until you are instructed to do so.• To ensure the best performance, check the manufacturing date on the new heat sink and make sure itdoes not exceed 2 years. Otherwise, wipe off the existing thermal grease and apply the new grease onto itfor optimal thermal performance.Notes:• PHMs are keyed for the socket where they can be installed and for their orientation in the socket.• See http://www.lenovo.com/us/en/serverproven/ for a list of processors supported for your server. Allprocessors on the system board must have the same speed, number of cores, and frequency.• Before you install a new PHM or replacement processor, update your system firmware to the latest level.See “Update the firmware” on page 92.• Installing an additional PHM can change the memory requirements for your system. See “Memory moduleinstallation rules” on page 57 for a list of microprocessor-to-memory relationships.• If you are going to install Intel Xeon 6230N, 6230T, or 5220T processor, use the heat sink with part number01KP652 or 01KP653.• Optional devices available for your system might have specific processor requirements. See thedocumentation that comes with the optional device for information.• The PHM for your system might be different than the PHM shown in the illustrations.To install a PHM, complete the following steps:Watch the procedure.
