Step 7. Remove the microprocessor:
a. Carefully lift the microprocessor straight up and out of the socket, without touching the
microprocessor contacts.
b. Place the microprocessor on a static-protective surface.
Attention: The pins on the sockets are fragile. Any damage to the pins might 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.

Replacing a microprocessor and heat sink

Use this information to replace 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:
• The server supports one Intel land grid array (LGA) 1150 dual-core or quad-core microprocessor. The
type, speed, and L3 cache of the microprocessor depends on the server model.
• Read the documentation that comes with the microprocessor to determine whether you have
to update the server firmware. To download the most current level of server firmware, go to
http://www.lenovo.com/support and http://www.ibm.com/support/fixcentral.
• The microprocessor uses an integrated voltage regulator on the system board.
• 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 244.
