Install a processor and heat sinkThis task has instructions for installing an assembled processor and heat sink, known as a processor-heat-sink module (PHM), a processor, and a heat sink. All of these tasks require a Torx T30 driver.Attention:• 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.Notes:• PHMs are keyed for the socket where they can be installed and for their orientation in the socket.• See http://www.lenovo.com/serverproven/ for a list of processors supported for your server. All processorson 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 “Firmware updates” on page 7.• Installing an additional PHM can change the memory requirements for your system. See “DIMMinstallation rules” on page 58 for a list of processor-to-memory relationships.• Optional devices available for your system might have specific processor requirements. See thedocumentation that comes with the optional device for information.Before you install a PHM:Note: The heat sink, processor, and processor retainer for your system might be different than those shownin the illustrations.1. Remove the existing PHM, if one is installed. See “Remove a processor and heat sink” on page 124.Note: Replacement processors come with both rectangular and square processor retainers. Arectangular retainer comes attached to the processor. The square retainer can be discarded.2. If you are replacing a heat sink, replace the processor retainer. Processor retainers should not be reused.a. Remove the old processor retainer.Chapter 3. Hardware replacement procedures 127
