Motherboard Installation
Installing the Motherboard
1. Review the documentation that came with your motherboard. Become familiar
with component placement, requirements, and precautions.
2. Power down the system and remove the power cords from the rear of the
power supplies. Remove the chassis cover as described in Section 5-3.
3. If necessary, remove the riser card. To do this, remove the two screws hold-
ing the card in place and lift the card from the chassis.
4. As required by your motherboard, install standoffs in any areas that do not
have a permanent standoff. To do this, compare the mounting holes in the
motherboard to those in the chassis. Add or remove standoffs as needed.
A. Place a hexagonal standoff screw through the bottom the chassis.
B. Secure the screw with the hexagon nut (rounded side up).
5. Lay the motherboard on the chassis aligning the permanent and optional
standoffs
6. Secure the motherboard to the chassis using the rounded, Phillips head
screws. Do not exceed eight pounds of torque when tightening the mother-
board.
7. Secure the CPU(s), heatsinks, and other components to the motherboard,
chassis, and/or backplane as needed.
8. Replace the chassis cover, plug the power cords into the rear of the power
supplies and power up the system.
