3. Using the green handle and the back edge of the motherboard tray, push down
firmly and equally while sliding the motherboard to the front of the chassis.
Tip – After installing the motherboard into the chassis, ensure that the motherboard
is correctly seated by gently lifting up on the handles. If the board moves upward,
then it is not correctly seated. Ensure that the motherboard tray sits flush with the
chassis floor. Also, check for binds and ensure that the bus bar screw holes are
correctly aligned with the bus bar at the front of the motherboard.
4. Tighten the captive screw that secures the motherboard to the front of its tray in
the chassis.
5. Install the four No. 2 Phillips screws that secure the motherboard to the bus bar.
Note – When you reinstall the motherboard, you must use the correct screws to
attach the motherboard to the bus bar.
