3. Replace the system backplane into the rear of the system.
a) Ensure that the two system backplane levers are open.
b) Support the system backplane by the bottom as you position the system backplane and insert it
into the system until it is fully seated.
Important:
• Use care when you insert the system backplane so that no damage occurs to the components at
the socket edge of the backplane.
• Ensure that the system backplane is fully seated and is all the way into the system.
• 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.
