Installing an additional microprocessor and heat sink

Use this information to install an additional 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:

• The server supports Intel scalable multi-core microprocessors which are designed for the LGA 2011 socket. Scalable up to ten cores with an integrated memory controller, quick-path interconnect and shared last cache. See https://static.lenovo.com/us/en/serverproven/index.shtml for a list of supported microprocessors.
• Both microprocessors must have the same QuickPath Interconnect (QPI) link speed, integrated memory controller frequency, core frequency, power segment, cache size, and type.
• Read the documentation that comes with the microprocessor to determine whether you must update the server firmware for the server. To download the most current level of server firmware and many other code updates for your server, complete the following steps:
  1. Go to http://datacentersupport.lenovo.com.
  2. Under Product support, click System x.
  3. Under Popular links, click Software and device drivers.
  4. Click System x3650 M4 BD to display the matrix of downloadable files for the server.
• (Optional) Obtain an SMP-capable operating system. For a list of supported operating systems and optional devices, see https://static.lenovo.com/us/en/serverproven/index.shtml.
• To order additional microprocessor optional devices, contact your sales representative or reseller.
• The microprocessor speeds are automatically set for this server; therefore, you do not have to set any microprocessor frequency-selection jumpers or switches.
• If you have to replace a microprocessor, call for service.
• 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.
• Do not remove the first microprocessor from the system board to install the second microprocessor.

Attention

• A startup (boot) microprocessor must always be installed in microprocessor socket 1 on the system board.
• To ensure correct server operation when you install an additional microprocessor, use microprocessors that are compatible and install at least one DIMM in a DIMM connector for microprocessor 2.

There are two types of microprocessor installation tools. The tools are similar in function and design, however Tool A has one setting for installing one size of microprocessor, and supports the following families of microprocessors: E5-26xx, E5-46xx. Installation Tool B has two settings for installing two different sizes of microprocessors. The settings that are marked on Tool B are “L” for smaller low core microprocessors, and “H” for larger high core microprocessors. Installation Tool B supports the following families of microprocessors: E5-26xx, E5-46xx, E5-26xx v2, E5-46xx v2. Microprocessor Installation Tools A and B are shown in the following illustration.

   1. Identify which release lever is labeled as the first release lever. Then release the microprocessor release lever by pressing down on the end, moving it to the side, and releasing it to the open (up) position.
   2. Open the second release lever on the microprocessor socket.
   3. Open the microprocessor retainer.
      Attention

      Do not touch the connectors on the microprocessor and the microprocessor socket.
9. Install the microprocessor on the microprocessor socket:
   1. Touch the static-protective package that contains the new microprocessor to any unpainted on the chassis or any unpainted metal surface on any other grounded rack component; then, carefully remove the microprocessor from the package.
   2. Release the sides of the cover and remove the cover from the installation tool. The microprocessor is preinstalled on the installation tool.

      Attention

      • Do not press the microprocessor into the socket.
      • Make sure that the microprocessor is oriented and aligned correctly in the socket before you try to close the microprocessor retainer.
      • Do not touch the thermal material on the bottom of the heat sink or on top of the microprocessor. Touching the thermal material will contaminate it.
10. Remove the microprocessor socket cover, tape, or label from the surface of the microprocessor socket, if one is present. Store the socket cover in a safe place.
