Netfinity 3500 M20 Microprocessors and SMP

The server comes with one microprocessor 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.

Compatible processor option part numbers

To install an additional microprocessor:

Attention:

• To avoid damage and ensure proper server operation when you install a new or an additional microprocessor, use microprocessors that have the same cache size and type, and the same clock speed. Microprocessor internal and external clock frequencies must be identical. Compatible processor option part numbers
• The server comes with one microprocessor installed in microprocessor connector U12. This is the startup (boot) microprocessor. If you install a microprocessor in microprocessor connector U11, that one becomes the startup processor and the microprocessor installed in connector U12 is the application processor.
• When you handle Electrostatic Discharge-Sensitive devices (ESD), take precautions to avoid damage from static electricity. For details on handling these devices, refer to the following Web site and use a search term of ESD: http://www.ibm.com/.

1. Review 'Safety information' in your user's guide or hardware maintenance manual.
2. Turn off the server and peripheral devices and disconnect all external cables and power cords; then remove the cover.
3. Remove the support bracket and the air baffle from behind the support bracket. Store them both in a safe place.
4. Lift up the release lever and remove the terminator card from the microprocessor connector.
5. Touch the static-protective package containing the new microprocessor to any unpainted metal surface on the server; then, remove the microprocessor from the package.
6. Orient the microprocessor over the microprocessor connector as shown in the following illustration. Carefully press the microprocessor into the connector. Note: Do not use excessive force when pressing the microprocessor into the connector.

7. Push the release lever [2] down to lock the microprocessor into place.
8. Install the heat sink on the microprocessor. To do this, first peel the plastic protective strip off the bottom of the heat sink. Make sure the square of thermal material is still on the bottom of the heat sink. Next, align and place the heat sink on top of the microprocessor. Finally, align and place the clip over the heat sink, then snap it into place.
9. 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.
10. Install the voltage regulator module (VRM) included in the microprocessor kit.
    Attention: Use of other VRMs might cause the server to overheat.
    a. Center the VRM over the VRM connector. Make sure that the VRM is oriented and aligned correctly.
    b. Press the VRM into the connector.
    Notes: If you remove the microprocessor later, remember to install the terminator card in the appropriate microprocessor connector and to remove the VRM. To remove the VRM, press down on the two release latches on the system board at the bottom of the VRM and gently lift the VRM away from the board.
11. If you have other options to install or remove, do so now; otherwise, replace the support bracket and the air baffle, then reinstall the server cover.
12. The F1 Configuration/Setup Utility will automatically run when the server is started. Save the new configuration settings.
13. Update your system BIOS to the latest level. Download the latest BIOS for your system.
14. Obtain and install an SMP-capable operating system.
15. Installation is complete.

To remove or replace a microprocessor:

NOTE: When you handle Electrostatic Discharge-Sensitive devices (ESD), take precautions to avoid damage from static electricity. For details on handling these devices, refer to the following Web site and use a search term of ESD: http://www.ibm.com/.

1. Do not use any tools when removing the microprocessor.
2. Review 'Safety information' in your user guide or hardware maintenance manual.
3. Turn off the server and peripheral devices and disconnect all external cables and power cords; then remove the cover.
4. Remove the support bracket and the air baffle from behind the support bracket. Store them both in a safe place.
5. Remove any heatsinks: NOTE: A thermal material is used between the heatsink and the processor. This material when heated and cooled causes the heatsink to adhere to the processor. Some force may be required to remove the heatsink.
   a. Press the handle of the heatsink clip down and toward the back until it releases, and lift it up and off the heatsink.
   b. Firmly grasp heat sink and pull upward. Attention: Do not use excessive force or tools to remove the heatsink.
   c. Discard the used heatsink.
6. Lift up the release lever and remove the microprocessor from the connector. Store the microprocessor in a static-protective bag for possible future use.
7. If you are installing a new microprocessor, refer to the "Installing an additional microprocessor" section (above). If you are not replacing the microprocessor, then you must reinstall the terminator card. Push the release lever down to lock the terminator card into place.
8. The F1 Configuration/Setup Utility will automatically run when the server is started. Save the new configuration settings.
9. Removal/Replacement is complete.
