Setting the microprocessor speed switches When you replace a microprocessor with one that has a different speed13, you must change the switch settings on the system board. Before you begin: Read "Electrical safety" on page 70 and "Handling static-sensitive devices" on page 71. Turn off the server and all other connected devices. Disconnect all external cables attached to the server; then, remove the server cover (see "Preparing to add options" on page 73). Locate the Flash BIOS in "Remote Administration" on page 52. Note: If you have not already done so, go to http://www.ibm.com/pc/support/ on the World Wide Web and download the appropriate flash update program. Review the applicable README files, and use this information to create a Flash BIOS Diskette. Perform the POST/BIOS (flash) update procedure (see "Remote Administration" on page 52 for additional information). 1. Locate the configuration switches (also known as rocker switches) on the system board. For more information, refer to the label inside the server, or see "System Board Illustration" on page 253. 2. To set the appropriate microprocessor speed, set switches 1 to 4 as shown in the following tables. It might be helpful to use the end of a small screwdriver to set the switch. Note: Switches 5 to 8 are not used for microprocessor speed settings. 13 MHz denotes internal clock speed of the microprocessor only; other factors also affect application performance. 258 Netfinity 3000 User's Handbook
