Processor installation and upgrade instructions - Netfinity 5100

IBM Netfinity 5100 microprocessors and SMP:

Your server comes with one microprocessor 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.

Important Notes:

• The microprocessor that is installed in microprocessor connector U3 is CPU 1 or processor 1 (see diagram below).
• If a microprocessor is installed in microprocessor connector U17, it is CPU 2 or processor 2.
• If the server has only one microprocessor installed, that microprocessor is installed in microprocessor connector U3 and is the startup (boot) processor.
• If more than one microprocessor is installed, the microprocessor with the lower stepping level is the startup processor and the microprocessor with the higher stepping level is the application processor. If both microprocessors have the same stepping level, the microprocessor installed in microprocessor connector U3 is the startup processor and the microprocessor installed in U17 is the application processor.
• You can determine the stepping levels of the installed microprocessors using the F1 Configuration/Setup utility program at system startup.
• NOTE: To avoid damage and ensure proper server operation when you install a new or an additional microprocessor, use microprocessors that have the same cache size and type, and the same clock speed. Microprocessor internal and external clock frequencies must be identical.
• Compatible processor upgrade option part numbers

How to install an additional microprocessor:

1. Review the "Safety Information" in your Users Guide or Hardware Maintainance Manual, and read the documentation that comes with the microprocessor.
2. Turn off the server and peripheral devices and disconnect all external cables and power cords; then remove the cover.
3. Remove the terminator card from the microprocessor connector. Store the terminator card in a safe place in the static-protective package that your new microprocessor is shipped in; you will need to install it again if you ever remove the microprocessor. Refer to the diagram below to locate the terminator card.
4. Touch the static-protective package containing the new microprocessor to any unpainted metal surface on the server; then, remove the microprocessor from the package.
5. Center the microprocessor over the microprocessor connector and carefully press the microprocessor into the connector.
   Note: To remove a microprocessor, pull upward on the microprocessor handle.
6. Install the voltage regulator module (VRM) included in the microprocessor kit by centering the VRM over the VRM connector (making sure the VRM is oriented and aligned correctly), then pressing the VRM into the connector. If you remove the microprocessor later, remember to reinstall the terminator card in the appropriate microprocessor connector, and to remove the VRM. NOTE: When installing or replacing a VRM, use only a VRM specified for use with the Netfinity 5100 server. Use of other VRMs might cause your server to overheat.
7. If you replaced the microprocessor with a different speed microprocessor, change switches 1-4 on the switch block to the appropriate settings, as shown in the following table. To avoid damage and ensure proper server operation when you install a new or an additional microprocessor, use microprocessors that have the same cache size and type, and the same clock speed. Microprocessor internal and external clock frequencies must be identical. See the "Processor Overview Diagram" below for the location of the switch block [4].
   
   Netfinity 5100 Microprocessor Speed Settings:
   

   Microprocessor Speed:	Switch 1:	Switch 2:	Switch 3:	Switch 4:
   667/133 MHz	On	On	Off	Off
   733/133 MHz	On	Off	Off	Off
   800/133 MHz	Off	On	On	On

   
   
8. If you have other options to install or remove, do so now; otherwise, reinstall the system cover.
9. Download and apply the latest system BIOS for the server.
10. Installation is complete.
