Installing an optional processor daughterboard and cache coherency filter cards


Installing an optional processor daughterboard and cache coherency filter cards

To install an optional processor daughterboard and the cache coherency filter cards:
  -Attention- Do not lift the processor housing assembly by the latches -8-.

  1.  If you have not already removed the processor housing assembly, do so now.
     Perform step 1 through step 7 and steps 1 and 2; 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.  Remove the empty processor cage -5-:

    1.  Squeeze and slide out the release latches -10- as far as they will go, until they reach the  unlocked position; then, release.
    2.  Lift the empty processor cage out of the processor housing assembly, and remove the spacers -6-.

      Note: When you are removing the processor cage from the processor housing assembly, be  sure that the processor cage release latches remain in place.
       Store the spacers in a safe place for future use.

  4.  Remove the fan guard -9-:

    1.  Remove the two screws from the sides of the fan guard.
    2.  Lift the fan guard off the processor housing assembly.
    3.  Rotate the fan guard away from the processors.
    4.  Slide the fan guard toward the processors to remove the tabs on the bottom of the fan guard  from the slots.
       Do not disconnect the power cables.

  5.  Install the two cache coherency filter cards in the two adjacent, vertical slots between the two processor  daughterboards on the processor controller board.
     For location, see 'Processor-controller board component locations'.
  6.  Reinstall the fan guard:

    1.  Ensure that the power cables are routed over the top of the retainer bracket that holds the two  cache coherency filter cards in place.
    2.  Slide the tabs on the bottom of the fan guard into the slots.
    3.  Place the fan guard on the processor housing assembly.
    4.  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'.
     For a layout of the processor daughterboard, see 'Processor-daughterboard component locations'.

  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 -10- 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 through step 7;  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 (above) step 2.
  17.  Reinstall the processor housing assembly by performing steps 1 through 7.
