Make sure that the daughter card is properly seated in the
connectors.
Using the hex key, secure the daughter card to the 8692 Series CPU
using four socket head screws (items 3 and 4 in the installation kit)
(see
"Securing the daughter card to the 8692 Series CPU" (page
139)).
Install the #2-56 x .625 screws first, followed by the #2-56 x .188
screws. See
"Securing the daughter card to the 8692 Series CPU"
(page 139)
for correct screw placement. You must insert the shorter
screws in the oval holes in the sheet metal daughter card bracket
and not through the daughter card. After you place the screw in the
hole, insert the hex key through the daughter card hole to secure
the screw in place.
CAUTION
Do not overtighten the screws. It is normal for a slight
space to be visible between the daughter card and the
standoffs.
