Lenovo HX1310 Installation And Service Manual page 176

• 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.ibm.com/support/ fixcentral.
• 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 168.
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 100.
Step 2. Turn off the server and peripheral devices and disconnect the power cords and 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 102.
Step 3. Remove the cover (see "Removing the cover" on page 104).
Step 4. Remove the air baffle (see "Removing the air baffle" on page 106).
