Microprocessor kit The server comes with one microprocessor installed on the processor board. When 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. Before you begin: Read "Safety information" on page 308. Thoroughly 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). The latest level of BIOS for the server is available through the World Wide Web and the IBM Bulletin Board System (BBS). See "Online support" on page iv for the appropriate World Wide Web addresses and bulletin-board telephone numbers. Obtain an SMP-capable operating system (optional). For a list of supported operating systems, see http://www.ibm.com/pc/us/compat/ on the World Wide Web. Notes: 1. The illustrations in this section might differ slightly from the hardware. 2. To avoid damage and ensure proper server operation when you install a new or additional microprocessor, use the same speed and voltage as those of the currently installed microprocessor. Microprocessor internal and external clock frequencies must be identical. 3. The microprocessor that is installed in the primary microprocessor connector is CPU or processor 1. If a microprocessor is installed in the secondary microprocessor connector, it is CPU or processor 2. If the server has only one microprocessor installed, that microprocessor is installed in the primary microprocessor connector and is the boot processor. If the server has two microprocessors installed, the microprocessor in the secondary microprocessor connector is the boot processor and the microprocessor in the primary microprocessor connector is the application processor. Refer to the following illustration while you perform the steps in this section. Netfinity 5500 - Type 8660 217
