• 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 137.
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 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 tool has two settings for installing two different sizes of microprocessors. The settings that are marked
on the tool are “L” for smaller low core microprocessors, and “H” for larger high core microprocessors.

To replace a microprocessor and heat sink, complete the following steps:
Step 1. Read the safety information that begins on “Safety” on page v and “Installation guidelines”
on page 75.
Step 2. Turn off the server and peripheral devices and disconnect all external cables.
Attention: When you handle static-sensitive devices, take precautions to avoid damage from
static electricity. For details about handling these devices, see “Handling static-sensitive devices”
on page 76.
Step 3. Remove the compute node (see “Removing a compute node from a chassis” on page 77).
Step 4. Remove the air baffle (see “Removing the air baffle” on page 86).
Step 5. Open the microprocessor socket release levers and retainer:
