Lenovo RD120 manual

Important: Dual-core and quad-core microprocessors are not interchangeable and cannot be used in the same server. For example, if the server has a dual-core microprocessor, you cannot install a quad-core microprocessor as the second microprocessor. Use the Configuration/Setup Utility program to determine the type and speed of the microprocessor that is currently installed in the server.

vThe server supports up to two microprocessors. If the server comes with one microprocessor, you can install a second microprocessor.

vBoth microprocessors must have the same cache size and type, front-side bus frequency, and clock speed. Microprocessor internal and external clock frequencies must be identical.

vWhen you install a microprocessor in microprocessor connector 2, you must also install the voltage regulator module (VRM), which comes with the microprocessor, in the VRM connector.

vRead the documentation that comes with the microprocessor to determine whether you must update the basic input/output system (BIOS) code for the server. To download the most current level of BIOS code and many other code updates 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 RD120, and click Continue.

4.Click Downloads and drivers to download firmware updates.

vTo order additional microprocessor optional devices, contact your Lenovo marketing representative or authorized reseller.

vThe microprocessor speeds are automatically set for this server; therefore, you do not have to set any microprocessor frequency-selection jumpers or switches.

vIf you have to replace a microprocessor, call for service.

vIf 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.

vDo not remove the first microprocessor from the system board to install the second microprocessor.

See “System-boardoptional-device connectors” on page 18 for the location of the microprocessor connectors and the VRM connector.

The following illustration shows how to install the second microprocessor on the system board.
