Attention Before you press the processor into the connector, make sure that the processor has the same orientation as the original A1 processor. c. Insert the processor 6 into the guides and gently press the processor into the connector. When the processor is correctly inserted, all the processor heat sinks in both processor cages face the same direction, toward connector A1. d. Rotate the processor latches 3 until they close and lock in place. 7. If you plan to install more than one processor, repeat step 3 on page 151 and step 6 on page 152 in this section. 8. If you replaced a defective processor, you must manually enable the processor slot in the Configuration/Setup utility program. In this case, the system does not automatically access the Configuration/Setup utility program to enable the processor slot. See "Processor settings" on page 31 for additional information. 9. If you are installing a processor daughterboard, continue with "Installing or replacing a processor daughterboard." If you are not installing a processor daughterboard, continue with the following steps. 10. Reinstall the processor-cage cover by inserting the cover tabs into the slots on the top of the processor cage. 11. Turn the four plastic fasteners on the processor-cage cover until they are in the locked position (one quarter-turn). You may use a flat-blade screwdriver or a coin. Attention Do not lift the processor housing assembly by the latches. 12. Reinstall the processor housing assembly as described in "Reinstalling the processor housing assembly" on page 159. Installing or replacing a processor daughterboard: You will need to install a second processor daughterboard if you plan to use more than four processors in the server. The additional processors must be installed on an optional processor daughterboard. Or, you might need to replace a processor daughterboard. Refer to the following illustration while you perform the steps in this section. In this illustration, the standard processor cage is installed in the processor housing Netfinity 8500R - Type 8681 153
