IBM 220 manual Installing and removing a microprocessor, Installing a microprocessor

Installing and removing a microprocessor

Your server comes with one microprocessor, which is installed on the system board. If you install an additional microprocessor kit, your 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) code. The latest level of BIOS code for your server is available through the World Wide Web. Refer to “Getting help, service, and information” on page 115 for the appropriate World Wide Web addresses.

2.Obtain an SMP-capable operating system (optional). For a list of supported operating systems, see http://www.ibm.com/pc/compat/ on the World Wide Web.

3.Your 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.

4.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.

5.The illustrations in this document might differ slightly from your server.

6.If necessary, see “System-board option connectors” on page 28 for connector locations.

Attention:

•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. See the ServerProven list at http://www.ibm.com/pc/compat for a list of microprocessors for use with your server.

•When you handle electrostatic discharge (ESD) sensitive devices, take precautions to avoid damage from static electricity. For details on handling these devices, see “Handling static-sensitive devices” on page 31.

Installing a microprocessor

To install an additional microprocessor, do the following:

1.Review the safety precautions in Statement 1 and Statement 5 in “Safety information” on page 32.

2.Turn off the server and peripheral devices, and disconnect all external cables and power cords; then, remove the side cover (see “Removing the side cover” on page 38 for details).

3.Carefully remove the support bracket assembly from the server (see “Removing the support bracket assembly” on page 39). Store the cover and the support
