Processor installation and removal - Netfinity 5000

Netfinity 5000 Microprocessors and SMP:

Your server comes with an Intel Pentium II microprocessor. This microprocessor incorporates MMX technology with built-in ECC level two (L2) cache.

When you install an additional microprocessor, your Netfinity 5000 can operate as a symmetric multiprocessing (SMP) server. With SMP, certain operating systems and application programs can distribute the processing load between microprocessors. This enhances performance for database and point-of-sale applications, integrated manufacturing solutions, and other applications.

Note: When you install a second microprocessor, it becomes the startup (boot) microprocessor.

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.

The voltage-regulator module (VRM) for the additional microprocessor plugs into a connector on the system board (see System Board Connectors for the location of the VRM connector). Because each microprocessor has specific power and voltage requirements, be sure to use the VRM that comes with the microprocessor.

Note: The voltage regulator function for the microprocessor that is shipped with your server is built into the system board.

If you select a setting for the frequency switch that is greater than the actual frequency of the microprocessor, you might damage the microprocessor. The frequency switch settings are shown in Table 5.

How to Install or Replace a Microprocessor:

This section gives the procedure for installing microprocessors. If you want to remove a microprocessor, reverse the order of the following steps.

Notes:

• The microprocessor in your server comes with an attached heat sink. The microprocessor plugs into the microprocessor socket on the system board and is stabilized with a plastic bracket attached to the system board.
• If you replace the microprocessor with one that has a different speed, you must change the switch settings on the system board. To locate the switches, see System Board Connectors. For information about the appropriate switch settings, see the table below, or refer to the label inside the server cover.
• Attention: If you select a setting for the frequency switch that is greater than the actual frequency of the microprocessor, you might damage the microprocessor.

1. Read the "Safety Information" in your User's Guide or Hardware Maintenance Manual.
2. If you have not done so, remove the server cover.
3. If you are installing an additional microprocessor, remove the terminator card from the secondary microprocessor connector. Otherwise, go to step 5.
4. Spread apart the posts of the secondary microprocessor connector bracket until the top of the terminator card is past the restraining latches.
5. Lift the terminator card out of the connector.
6. Carefully remove the microprocessor from the static-protective package.
7. If you are replacing a microprocessor, remove the existing microprocessor from its socket. Otherwise, go to step 11.
8. Locate the microprocessor socket on the system board. (See the illustration in System Board Illustration.)
9. Place your index fingers on the small retainer tabs on the top of the microprocessor, and push in toward the microprocessor until the tabs release.
   
10. Lift the microprocessor out of the connector.
    
11. Store the old microprocessor in a static-protective package.
12. Touch the static-protective package that contains the new microprocessor to any unpainted metal surface in the server; then, remove the new microprocessor.
13. Press inward on the retainer tabs until they click into place. For the location of the retainer tabs, see the illustration above.
14. Align the new microprocessor with the microprocessor connector on the system board and slide it into the guides.
15. Press the microprocessor down until it snaps into place and is fully seated in the connector.
    
16. Pull outward on the retainer tabs.
    
17. If you replaced the microprocessor with one that has a different speed, you must change the switch settings on the system board. To locate the switches, see System Board Connectors. Note: If the processor in you system does not react to switch changes, it is not an error.
    
18. Because you installed a new microprocessor in your server, you must reconfigure your server using the Configuration/Setup Utility at system startup. When the system restarts, it will automatically enter the Configuration/Setup Utility. Save the new configuration settings, and exit the utility.
19. Because you installed a new microprocessor in your server, you might need to make changes to your operating system.
    
    If your operating system does not support SMP, install one of the SMP operating systems that your server supports. For a list of supported operating systems, see http://www.ibm.com/servers/eserver/serverproven/compat/us/
    
    If your operating system does support SMP, refer to your operating-system documentation. You might need to make changes so that the operating system recognizes the new microprocessor.
    
    On some operating systems, if you install a second microprocessor it might be necessary to reinstall the operating system. See the documentation that comes with the new microprocessor.
    
    
20. Upgrade the system BIOS to the latest level. Click here to download the latest BIOS for your system.
21. If you want to install or remove any other options, do so now. Otherwise, installation is complete.
