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 2 on page 58 through step 8 on page 59 and steps 1 and 3 on
page 60; then, return here.
2. If you have not already removed the processor-cage cover
1
, do so now.
Rotate the four fasteners

to the unlocked position; then, lift the cover and
set it aside.
3. Remove the empty processor cage
5
:
a. Squeeze and slide out the release latches
1
as far as they will go, until
they reach the unlocked position; then, release.
b. Lift the empty processor cage out of the processor housing assembly, and
remove the spacers

.
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
:
a. Remove the two screws from the sides of the fan guard.
b. Lift the fan guard off the processor housing assembly.
c. Rotate the fan guard away from the processors.
d. 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” on
page 107.
6. Reinstall the fan guard:
a. Ensure that the power cables are routed over the top of the retainer bracket
that holds the two cache coherency filter cards in place.
b. Slide the tabs on the bottom of the fan guard into the slots.
c. Place the fan guard on the processor housing assembly.
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
