5 Close both latches simultaneously until they are flush against the
faceplate. Refer to the figure “Closed card latches on a CP, FP, or blank
processor card” (page 577).
When a latch will not sit flush against the faceplate, do not force it. Fully
open both latches, slide the card out to disengage contact from the
backplane, and return to step 4.
When a latch does not sit flush after a second attempt, abort the seating
and contact your next higher level of technical support.
CAUTION
Risk of damage to the backplane from seating a card
When latching a card into its final seating position, the
card latches must be closed simultaneously to ensure that
the card evenly engages the gaskets and pins on the
backplane. Otherwise, improperly seating a card can
damage the backplane hardware such that the slot becomes
unusable. Restoring a slot to service from this kind of
damage means replacing the shelf assembly.
