Important: Always use the microprocessor installation tool to install a microprocessor. Failing to use
the microprocessor installation tool may damage the microprocessor sockets on the system board. Any
damage to the microprocessor sockets may require replacing the system board.
• The server supports up to two Intel Xeon™ E5-2600 series multi-core microprocessors, which are
designed for the LGA 2011 socket. See http://www.lenovo.com/ serverproven/ for a list of supported
microprocessors.
• Do not mix microprocessors with different cores in the same server.
• The first microprocessor must always be installed in microprocessor socket 1 on the system board.
• When one microprocessor is installed, the air baffle must be installed to provide proper system cooling.
• Do not remove the first microprocessor from the system board when you install the second
microprocessor.
• When you install the second microprocessor, you must also install additional memory and the fourth fan.
See “Installing a memory module” on page 50 for details about the installation sequence.
• To ensure proper server operation when you install an additional microprocessor, use microprocessors
that have the same QuickPath Interconnect (QPI) link speed, integrated memory controller frequency, core
frequency, power segment, internal cache size, and type.
• Mixing microprocessors of different stepping levels within the same server model is supported.
• When mixing microprocessors with different stepping levels within the same server model, you do not
have to install the microprocessor with lowest stepping level and features in microprocessor socket 1.
• Both microprocessor voltage regulator modules are integrated on the system board.
• Read the documentation that comes with the microprocessor to determine whether you have to update
the server firmware. To download the latest level of server firmware and other code updates for your
server, go to http://www.lenovo.com/support.
• The microprocessor speeds are automatically set for this server; therefore, you do not have to set any
microprocessor frequency-selection jumpers or switches.
• If the thermal-grease protective cover (for example, a plastic cap or tape liner) is removed from the heat
sink, do not touch the thermal grease on the bottom of the heat sink or set down the heat sink. For more
information about applying or working with thermal grease, see “Thermal grease” on page 135.
Note: Removing the heat sink from the microprocessor destroys the even distribution of the thermal
grease and requires replacing the thermal grease.
• To order an additional optional microprocessor, contact your sales representative or reseller.
There are two types of microprocessor installation tools. The tools are similar in function and design,
however Tool A has one setting for installing one size of microprocessor, and supports the following
families of microprocessors: E5-26xx, E5-46xx. Installation Tool B has two settings for installing two
different sizes of microprocessors. The settings that are marked on Tool B are “L” for smaller low core
microprocessors, and “H” for larger high core microprocessors. Installation Tool B supports the following
families of microprocessors: E5-26xx, E5-46xx, E5-26xx v2, E5-46xx v2.
Microprocessor Installation Tools A and B are shown in the following illustration.
