Figure 209. Lift microprocessor out of the socket
Step 7.
If you do not intend to install a microprocessor on the socket, install the socket cover that you
removed before on the microprocessor socket.
Attention:
The pins on the socket are fragile. Any damage to the pins may require replacing the
system board.
If you are instructed to return the server component or optional device, follow all packaging instructions,
and use any packaging materials for shipping that are supplied to you.
Installing a microprocessor and heat sink
Use this information to install a microprocessor and heat sink.
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.
• The server supports certain Intel Xeon scalable multi-core microprocessors, which are designed for
the LGA 2011 socket. These microprocessors are 64-bit dual-core or quad-core microprocessors
with an integrated memory controller, quick-path interconnect, and shared last cache. See
http://www.lenovo.com/ serverproven/ for a list of supported microprocessors.
• Do not mix microprocessors with different cores in the same server.
• The server supports up to two microprocessors when the microprocessor 2 expansion board is installed.
Note:
Microprocessor 2 expansion board is supported when the second microprocessor is installed.
• When two microprocessors are installed, the air baffle and fan 2 must be installed to provide proper
system cooling.
• When you install the second microprocessor, you must also install additional memory, the air baffle, and
fan 2. See “Memory module installation” on page 262 for details about the installation sequence.
