d. Reinstall the two screws that you removed in step 4a to secure the fan guard. 7. Touch the static-protective package containing the new processor daughterboard to any unpainted metal surface on the server; then, remove the new processor daughterboard 7 from its static-protective package. 8. Align the processor-daughterboard connector with the keyed connector on the processor controller board. Note For the location of the processor-daughterboard connectors on the processor controller board, see "Processor-controller board component locations" on page 140. For a layout of the processor daughterboard, see "Processor-daughterboard component locations" on page 143. 9. Firmly press the processor daughterboard 7 down into the keyed connector on the processor controller board. Push in the center of the board, until the processor daughterboard is fully seated. 10. Ensure that the two processor cage release latches are still in the unlocked (pulled out) position. 11. Align the processor cage with its tabs over the corresponding slots on the processor daughterboard. Match the labels on the processor cage with the corresponding labels on the fan guard 9 ; for example, A1/A1. 12. Firmly press the processor cage down into the slots in the processor housing assembly, until the processor cage is fully seated. 13. Squeeze and firmly push the release latches 1 back into the locked position; then, release. Attention Ensure that the release latches are in the fully locked position. 14. Install processors 4 in the desired connectors, as described in step 3 on page 151 through step 7 on page 153; then, return here. 15. Install terminator cards 3 in the connectors that do not contain processors. The arrows on the terminators must face toward the large connector on the processor housing assembly and away from the fan guard. 16. Reinstall the processor-cage cover by reversing step 2 on page 155. 17. Reinstall the processor housing assembly by performing steps 1 through 7 on page 159.
