daughterboard; then, remove the processor daughterboard from the processor housing assembly. 7. Remove the new processor daughterboard 7 from its static-protective bag. 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. 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. 11. Firmly press the processor cage down into the slots on the processor housing assembly, until the processor cage is fully seated. 12. 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. 13. Install processors 4 in the desired connectors, as described in step 3 on page 151 through step 7 on page 153; then, return here. 14. 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. 15. If you removed the processor-daughterboard extraction tool in step 5 on page 157, replace the processor-daughterboard extraction tool on processor cage A, behind processor A4. Otherwise, store the tool in a safe place for future use. 16. Reinstall the processor-cage cover by performing steps 10 and 11 on page 153. 17. Reinstall the processor housing assembly as described in "Reinstalling the processor housing assembly" on page 159. 158 Netfinity Server HMM
