Netfinity 3000 - Microprocessor Speed Switch Settings

Applicable to: World-Wide

Microprocessor Speed Switch Settings:
When you replace a microprocessor with one that has a different speed* ( See Note below), you must change the switch settings on the system board.

Note * : MHz denotes internal clock speed of the microprocessor only; other factors also affect application performance.

Before you begin: - Read "Safety Information". - Power-off the server and all other connected devices. - Disconnect all external cables attached to the server; then, remove the server cover. - Locate the Flash Utility Diskette that you created in "Remote Administration".

Note If you have not already done so, go to http://www.pc.ibm.com/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 Utility Diskette. Perform the POST/BIOS (flash) update procedure (see "Remote Administration" 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".

2. To set the appropriate microprocessor speed, set switches 1 to 4 as shown in the following illustration. 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.

Attention The following illustration is for reference only. Before you change the settings for switches 1 through 4, be sure that you check the orientation of the server system board to correctly identify the switch number locations. If you change the settings for the wrong switches, you might seriously damage server components or options.

3. If you receive the error code 167 after you install a new microprocessor, run the Flash Utility program. Insert the Flash Utility Diskette into the primary diskette drive and reboot the system. Follow the instructions in the program.

4. After changing configuration switch settings, you must reconfigure the server. After reassembling the server (see "Completing the Installation"), use the Configuration/Setup Utility program to reconfigure the server. For more information, see "Configuration/Setup Utility Program Menus".
