Installing a microprocessor and heat sink

Use this information to install a microprocessor and heat sink in the blade server.

The following notes describe the type of microprocessor that the server supports and other information that you must consider when you install a microprocessor:

• Each microprocessor socket must always contain either a socket cover and heat-sink filler or a microprocessor and heat sink. If the blade server has only one microprocessor, it must be installed in microprocessor socket 1.
• If you are installing a second microprocessor, make sure that the microprocessors are identical.
• Before you install a new microprocessor, download and install the most current level of UEFI code (see Updating firmware and device drivers).
• When you install a second microprocessor, you might have to install additional memory, or redistribute memory across the DIMM connectors (see Installing a memory module).
• The microprocessor installation tool might become worn after several uses. Make sure that the tool can hold the microprocessor securely if you are reusing an existing microprocessor installation tool. Do not return the tool with other parts that you are returning.

The following illustration shows how to install a microprocessor and heat sink in the blade server.

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.

Attention:

1. Do not use any tools or sharp objects to lift the release levers on the microprocessor socket. Doing so might result in permanent damage to the system board.
2. Do not touch the contacts in the microprocessor socket. Touching these contacts might result in permanent damage to the system board.

To install a microprocessor and heat sink, complete the following steps:

1. Remove the heat-sink filler, if one is present.
2. If you are not installing a new microprocessor and a new heat sink, remove the thermal grease from the heat sink and microprocessor; then, apply new thermal grease before installation (see Thermal grease).
   Attention: Do not use any tools or sharp objects to lift the release levers on the microprocessor socket. Doing so might result in permanent damage to the system board.
3. Open the microprocessor socket release levers and retainer:
   
   
   
   1. Note which release lever is labeled as the first release lever to open and open it.
   2. Open the second release lever on the microprocessor socket.
   3. Open the microprocessor retainer.
4. Install the microprocessor in the microprocessor socket:
   1. If a dust cover is installed over the microprocessor socket, lift the dust cover from the socket. Store the dust cover in a safe place.
   2. Touch the static-protective bag that contains the new microprocessor to any unpainted surface on the BladeCenter chassis or any unpainted metal surface on any other grounded rack component; then, carefully remove the microprocessor and the installation tool from the package.
   3. Release the sides of the cover and remove the cover from the installation tool. The microprocessor is preinstalled on the installation tool.
      
      
      

      Note: Do not touch the microprocessor contacts. Contaminants on the microprocessor contacts, such as oil from your skin, can cause connection failures between the contacts and the socket.
   4. Align the installation tool with the microprocessor socket. The installation tool rests flush on the socket only if properly aligned.
      
      
      
   5. Install the microprocessor using the following instructions for your installation tool.
      • If using Installation Tool A, twist the handle on the microprocessor tool assembly counterclockwise to the open position to insert the microprocessor into the socket, and lift the installation tool out of the socket.
      • If using Installation Tool B, twist the handle of the installation tool assembly counterclockwise until the microprocessor is inserted into the socket, and lift the installation tool out of the socket. The following illustration shows the tool handle in the open position.

      Attention:

      • Do not press the microprocessor into the socket.
      • Do not touch exposed pins of the microprocessor 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.
5. Close the microprocessor socket release levers and retainer:
   
   
   
   1. Close the microprocessor retainer on the microprocessor socket.
   2. Identify which release lever is labeled as the first release lever to close and close it.
   3. Close the second release lever on the microprocessor socket.
   4. If a socket cover is installed over the microprocessor retainer, it is released as you close the retainer. Remove the socket cover from the blade server and store it in a safe place.
6. If you are reinstalling a heat sink that was removed from the blade server, complete the following steps.
   Attention: Do not touch the thermal material on the bottom of the heat sink. Touching the thermal material will contaminate it. If the thermal material on the microprocessor or heat sink becomes contaminated, wipe off the contaminated thermal material on the microprocessor or heat sink with the alcohol wipes and reapply clean thermal grease to the heat sink.
   1. Make sure that the thermal material is still on the bottom of the heat sink and on the top of the microprocessor.
   2. Position the heat sink over the microprocessor. The heat sink is keyed to assist with proper alignment.
   3. Align and place the heat sink on top of the microprocessor in the retention bracket, thermal material side down. Press firmly on the heat sink.
   4. Align the screws on the heat sink with the holes on the heat-sink retention module.
   5. Press firmly on the captive screws and tighten them with a screwdriver, alternating among the screws until they are tight. If possible, each screw should be rotated two full rotations at a time. Repeat until the screws are tight. Do not overtighten the screws by using excessive force. If you are using a torque wrench, tighten the screws to 8.5 Newton-meters (Nm) to 13 Nm (6.3 foot-pounds to 9.6 foot-pounds).
7. If you are installing a new heat sink, complete the following steps.
   Attention:

   • Do not set down the heat sink after you remove the plastic cover.
   • Do not touch the thermal material on the bottom of the heat sink. Touching the thermal material will contaminate it. If the thermal material on the microprocessor or heat sink becomes contaminated, contact your service technician.
   1. Remove the plastic protective cover from the bottom of the heat sink.
   2. Position the heat sink over the microprocessor. The heat sink is keyed to assist with proper alignment.
   3. Align and place the heat sink on top of the microprocessor in the retention bracket, thermal material side down.
   4. Press firmly on the heat sink.
   5. Align the screws on the heat sink with the holes on the heat-sink retention module.
   6. Press firmly on the captive screws and tighten them with a screwdriver, alternating among the screws until they are tight. If possible, each screw should be rotated two full rotations at a time. Repeat until the screws are tight. Do not overtighten the screws by using excessive force. If you are using a torque wrench, tighten the screws to 8.5 Newton-meters (Nm) to 13 Nm (6.3 foot-pounds to 9.6 foot-pounds).
8. Install the optional expansion unit, if you removed one from the blade server to replace the battery (see Installing an optional expansion unit for instructions).
9. Install the cover onto the blade server (see Installing the blade server cover).
10. Install the blade server into the BladeCenter unit (see Installing the blade server in a BladeCenter unit).
