The following notes describe the type of microprocessor
that the server supports and other information that you must consider
when you install a microprocessor and heat sink.
- Microprocessors are to be installed only by trained technicians.
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.
- Be extremely careful, the microprocessor socket contacts are very
fragile. Do not touch the microprocessor socket contacts. Contaminants
on the microprocessor contacts or microprocessor socket contacts,
such as oil from your skin, can cause connection failures between
the contacts and the socket.
- Do not allow the thermal grease on the microprocessor and heat
sink to come in contact with anything. Contact with any surface can
contaminate the thermal grease and the microprocessor socket.
- Do not use any tools or sharp objects to lift the locking levers
on the microprocessor socket. Doing so might result in permanent damage
to the system board.
- Each microprocessor socket must always contain either a socket
cover or a microprocessor and heat sink.
- Be sure to use only the installation tools provided with the new
microprocessor to remove or install the microprocessor. Do not use
any other tool.
- When installing multiple microprocessors, open one microprocessor
socket at a time to avoid damaging other microprocessor socket contacts.
- The microprocessor installation tool has the microprocessor installed
on the tool, and may have a protective cover over the microprocessor.
Do not use the tool, or remove the cover until you are instructed
to do so.
Note: Be sure to use the installation tool that comes with
your microprocessor installation tool assembly.
- The server supports up to two multi-core microprocessors. See the Lenovo ServerProven website for a list of supported
microprocessors.
- 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, the fourth and sixth fans. See Installing a memory module for details about the installation
sequence.
- Do not mix microprocessors with different cores in the same server.
- 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 the Fix Central website.
- 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.
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 Lenovo
sales representative or Lenovo reseller.
The installation tool has two settings for installing two
different sizes of microprocessors. The settings that are marked on
tool are L
for smaller low core microprocessors, and H
for larger high core microprocessors. Installation tool supports
the following families of microprocessors: E5-26xx, E5-46xx, E5-26xx
v2, E5-46xx v2.
To replace a microprocessor and heat sink, complete
the following steps:
