Installing A Second Microprocessor - Lenovo TD200 - ThinkServer - 3809 Hardware Maintenance Manual

9. Rotate the rear and front adapter-retention brackets to the closed position.
10. Close the bezel. Install the side cover (see "Installing the side cover" on page 252).
Lock the side cover.
Reconnect the external cables and power cords; then, turn on the attached devices and turn on the server.
If you have other options to install or remove, do so now; otherwise, go to "Completing the installation" on
page 249.

Installing a second microprocessor

The following notes describe the type of microprocessor that the server supports and other information that
you must consider when installing a microprocessor:
• The server comes with one microprocessor installed, but supports up to two microprocessors.
Note: A microprocessor must be installed and removed only by a trained service technician.
• To download the most current level of the firmware for your server, complete the following steps:
1. Go to: http://www.lenovo.com/support.
2. Enter your product number (machine type and model number) or select Servers and Storage from
the Select your product list.
3. From Family list, select ThinkServer TD200, and click Continue.
4. Click Downloads and drivers to download firmware updates.
• The first microprocessor must always be installed in microprocessor socket 1.
• When one microprocessor is installed, a heat sink filler is not required for microprocessor socket 2,
however, 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. See "Installing a
memory module" on page 211.
• The first microprocessor voltage regulator module (VRM) is integrated on the system board.
• When you install a second microprocessor, you must also install the voltage regulator module (VRM),
which comes with the microprocessor option kit, in the VRM connector on the system board.
• Some models support dual-core microprocessors or quad-core microprocessors. Do not mix dual-core
microprocessors and quad-core microprocessors in the same system. Install all dual-core or all quad-core
microprocessors in the 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. You can use the Setup Utility to determine the
specific type of microprocessor that is installed on the system board.
• Mixing microprocessors of different stepping levels within the same server model is supported. You do not
have to install the microprocessor with the lowest stepping level and features in microprocessor socket 1.
• 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.
• If you have to replace a microprocessor, call for service.
• To order additional microprocessor options, contact your Lenovo marketing representative or authorized
reseller.
