Refer to the illustration that immediately precedes "Installing an optional processor daughterboard and cache coherency filter cards" on page 155 while you perform the steps in this section. Attention: Do not lift the processor housing assembly by the latches. 1. If you have not already removed the processor housing assembly, do so now. Perform step 1 on page 149 through step 7 on page 150 and steps 1 and 2 on page 151; then, return here. 2. If you have not already removed the processor-cage cover 1 , do so now. Rotate the four fasteners 2 to the unlocked position; then, lift the cover and set it aside. 3. Open the latches at the top of the processor in connector A1, and remove the processor. Place it on a flat, static-protective surface. Repeat these actions for the remaining processors and terminator cards in the processor cage. 4. Remove the processor cage: a. Squeeze and slide out the release latches 1 as far as they will go, until they reach the unlocked position; then, release. as they will go, until they reach the unlocked position. b. Lift the processor cage out of the processor housing assembly, and place it on a flat, static-protective surface. 5. If necessary, remove the processor-daughterboard extraction tool from processor cage A (behind processor A4); then, place the processor-daughterboard extraction tool under and against the processor daughterboard, as shown, in the area marked Use extraction tool here. 6.
