Removing and installing the Microprocessor - IBM eServer xSeries 220

Content

The server comes with one microprocessor, which is installed on the system board. If you install an additional microprocessor kit, the server can operate as a symmetric multiprocessing (SMP) server. With SMP, certain operating systems and application programs can distribute the processing load between the microprocessors. This enhances performance for database and point-of-sale applications, integrated manufacturing solutions, and other applications.

Notes:

1. Before you install a new microprocessor, review the documentation that comes with the microprocessor, so that you can determine whether you need to update the server basic input/output system (BIOS).
2. Download the latest level of BIOS for the xSeries 220 (8645)
3. Click here to download the latest level of BIOS for the xSeries 220 (8646)
4. Obtain an SMP-capable operating system (optional). Click here to review supported operating systems.
5. The server comes with one microprocessor, which is installed in microprocessor connector U12 (the microprocessor connector that is closer to the power supply). This is the startup (boot) microprocessor. If you install a microprocessor in microprocessor connector U11, that one becomes the startup microprocessor, and the microprocessor that is installed in microprocessor connector U12 is the application microprocessor. You must also install a VRM when you install a microprocessor.
6. If you are installing a microprocessor that has a speed of 933 MHz or higher, you must also install a fan sink and connect the fan-sink power cable to the system board.
   
   Note: The illustrations in this document might differ slightly from the server.
   

WARNING: To avoid damage and ensure proper server operation when you install a new or additional microprocessor, use microprocessors that have the same cache size and type and the same clock speed. Microprocessor internal clock frequencies and external clock frequencies must be identical. Click here to review a list of supported microprocessors.

When you handle electrostatic discharge (ESD) sensitive devices, take precautions to avoid damage from static electricity.

1. Turn off the server and peripheral devices, and disconnect all external cables and power cords; then, remove the cover.
2. Carefully remove the support bracket assembly. Store the cover and the support bracket assembly it in a safe place.
   Lift the release lever and remove the terminator card from the microprocessor connector.
3. Install the microprocessor:
   1. Touch the static-protective package containing the new microprocessor to any unpainted metal surface on the server; then, remove the microprocessor from the package.
   2. Position the microprocessor over the microprocessor connector, as shown in the following illustration.
      
      
   3. Carefully press the microprocessor into the connector.
      WARNING: To avoid bending the pins, do not use excessive force when pressing the microprocessor into the connector.
      
      
4. Push the release lever down to lock the microprocessor into place.
5. If you are installing a microprocessor that has a speed of 933MHz or higher, continue with step 7. If you are installing a microprocessor that has a speed lower than 933 MHz, continue with step 6.
6. If you are installing a microprocessor that has a speed lower than 933MHz, install the heat sink onto the microprocessor:
   
   
   
   
   1. Peel the plastic protective strip off the bottom of the heat sink.
   2. Make sure that the square of thermal material is still on the bottom of the heat sink.
   3. Align and place the heat sink on top of the microprocessor.
   4. Align and place the heat-sink retainer (clip) over the heat sink; then, snap it into place. Continue with step 8.
      
      
7. If you are installing a microprocessor that has a speed of 933MHz, install a fan sink onto the microprocessor and connect the fan-sink power cable to the system board:
   
   
   
   
   1. Peel the plastic protective strip off the bottom of the fan sink. Make sure that the square of thermal material is still on the bottom of the fan sink.
   2. Align and place the fan sink on top of the microprocessor.
   3. Align and place the fan-sink retainer (clip) over the fan sink.
   4. Insert a small, flat-blade screwdriver into the tab on the fan-sink retainer.
   5. Press down and in with the screwdriver handle to snap the fan-sink retainer into place in the slot on the microprocessor, over the fan sink.
   6. Connect the built-in fan-sink power cable to the appropriate connector on the system board:
      1. If you installed the microprocessor in connector U11, connect the fan-sink power cable to connector J2.
      2. If you installed the microprocessor in connector U12, connect the fan-sink power cable to connector J3.
         
         
8. Place the terminator card in the static-protective package that the new microprocessor was shipped in, and store it in a safe place. You will need to install the terminator card again if you ever remove the microprocessor and do not replace it with another microprocessor.
9. Install the VRM that is included in the microprocessor kit.
   
   WARNING: Use of other VRMs might cause the server to overheat.
   1. Center the VRM over the appropriate VRM connector:
      1. If you installed the microprocessor in connector U11, press down on the
         latches on either side of connector J12, and install the VRM in connector J12.
      2. If you installed the microprocessor in connector U12, press down on the
         latches on either side of connector J42, and install the VRM in connector J42.
         
         Note: If the server is a hot-swap model, reinstall the VRM in connector J42 after you reinstall the support bracket assembly.
         
         
   2. Make sure that the VRM is oriented and aligned correctly.
   3. Press the VRM into the connector.
      
      Note: If you remove the microprocessor later, remember to install the terminator card in the appropriate microprocessor connector and to remove the VRM from the appropriate VRM connector.
      
      
10. If you have other options to install or remove, do so now; otherwise, replace the support bracket assembly; then, go to 'Installing the cover'.

Do not use any tools when removing the microprocessor; however, you will need a small, flat-blade screwdriver to remove the fan-sink retainer (clip).
