11. Insert the DIMM into the connector. Firmly press the DIMM straight down into the connector by applying pressure on both ends of the DIMM simultaneously. The retaining clips snap into the locked position when the DIMM is firmly seated in the connector. If there is a gap between the DIMM and the retaining clips, the DIMM has not been correctly installed. Open the retaining clips and remove the DIMM; then, reinsert it. 12. Push the drive cage outward, and press in on the drive-cage release lever; then, rotate the drive cage completely into the chassis. 13. Press down on the power-supply release latch and rotate the power supply into the chassis. Return the power-supply handle to the closed position. If you have other options to install or remove, do so now. Otherwise, return the computer to the upright position. Replace the side cover (see "Replacing the side cover" on page 59). Installing a second microprocessor The computer comes with one microprocessor installed on the system board. The computer supports up to two microprocessors. Note: When installing a microprocessor option, lay the computer on its side. The following notes describe information that you must consider when installing an additional microprocessor in the computer: v Read the documentation that comes with the microprocessor to determine whether you must update the computer BIOS code. The most current level of BIOS code for the computer is available from http://www.ibm.com/support/. v To ensure proper computer operation, use microprocessors that have the same cache size and type, and the same clock speed. Microprocessor internal and external clock frequencies must be identical. You can use the Configuration/Setup Utility program to determine the specific type of microprocessor on the system board. Important: The first microprocessor must always be installed in the microprocessor 1 socket. v The microprocessor speeds are automatically set for this computer; therefore, you do not have to set any microprocessor frequency-selection jumpers or switches. 52 IBM IntelliStation Z Pro Type 9228: User's Guide

BIOS
code.
The
