3. Grasping the motherboard by the handle, place it into the chassis.
4. Hold the cables off to the side while grasping the handle on the motherboard
and sliding it toward the back of the chassis.
5. Reinsert and tighten the four bus bar screws that secure the motherboard to the
power supply backplane.
See "Install the Power Supply Backplane" on page
Note – Using a No. 2 screwdriver, tighten the bus bar screws until the power supply
backplane and the motherboard securely fasten to the bus bars.
6. Reinstall the System Remind button assembly (air divider) by sliding it into the
chassis.
Caution – After replacing the motherboard, inspect the dividing wall gasket, and
then install the plastic dividing wall securely. This dividing wall maintains a
pressurized seal between the server cooling zones. Without this pressurized seal, the
power supply fans will not be able to draw enough air to cool the drives properly.
7. Reinstall all memory risers.
