Note: You must remove and replace the system backplane at a flat angle. The ventilation holes in
the top cover can come into contact with the DIMMs in the system backplane if the insertion of the
backplane is at an angle or is rushed. As a result of possible contact, DIMMs can be scratched and
can leave residue on the top cover.
