Installing Microprocessors Installing or Replacing Microprocessors This section gives the procedure for installing microprocessors. If you want to remove a microprocessor, reverse the order of the following steps. Before you begin: Read "Electrical Safety" on page 54 and "Handling Static-Sensitive Devices" on page 55. Thoroughly review the documentation that comes with the microprocessor, so that you can determine whether you need to update the server BIOS. ServerGuide includes IBM Update Connector, a dial-up program that keeps your BIOS and device drivers current. You can also obtain the latest level of BIOS for your server through the World Wide Web and the IBM PC Company Bulletin Board System (BBS). See Chapter 6, "Getting Help, Service, and Information" on page 183 for the appropriate World Wide Web addresses and bulletin board telephone numbers. Obtain an SMP operating system (optional). For a list of supported operating systems, see http://www.us.pc.ibm.com/server/ on the World Wide Web. Read "Accessing the System Board" on page 58. Attention: If you install an additional microprocessor that is different from the currently installed microprocessor, your server operation might be unreliable. To prevent this, use a microprocessor with the same internal and external clock speed, and the same cache size and voltage requirements as those of the currently installed microprocessor. Microprocessor internal and external clock frequencies and cache size must be identical. If you select a setting for the frequency jumper that is greater than the actual frequency of the microprocessor, you might damage the microprocessor. 90 Netfinity 3500 User's Handbook
