3.The server comes with one microprocessor, which is installed in microprocessor connector U12 (the microprocessor connector that is closer to the power supply). This is the startup (boot) microprocessor. If you install a microprocessor in microprocessor connector U11, that one becomes the startup microprocessor, and the microprocessor that is installed in microprocessor connector U12 is the application microprocessor. You must also install a VRM when you install a microprocessor.
4.If you are installing a microprocessor that has a speed of 933 MHz or higher, you must also install a fan sink and connect the
5.The illustrations in this document might differ slightly from your server.
6.If necessary, see “System board options connectors” on page 55 for connector locations.
Attention:
•To avoid damage and ensure proper server operation when you install a new or additional microprocessor, use microprocessors that have the same cache size and type and the same clock speed. Microprocessor internal clock frequencies and external clock frequencies must be identical. See the ServerProven list at http://www.ibm.com/pc/compat for a list of microprocessors for use with the server.
•When you handle electrostatic discharge (ESD) sensitive devices, take precautions to avoid damage from static electricity. For details on handling these devices, see “Handling electrostatic
Installing a microprocessor
To install an additional microprocessor, do the following:
1.Review the safety precautions in Statement 1 and Statement 5 in “Safety information” on page 133.
2.Turn off the server and peripheral devices, and disconnect all external cables and power cords; then, remove the cover (see “Removing the side cover” on page 59 for details).
3.Carefully remove the support bracket assembly (see “Removing the support bracket assembly” on page 61). Store the cover and the support bracket assembly it in a safe place.
4.Lift the release lever and remove the terminator card from the microprocessor connector.
