Installing the Motherboard
To install the motherboard, the expansion card assembly needs to be removed first.
1. Review the documentation that came with your motherboard. Become familiar with
component placement, requirements, precautions, and cable connections.
2. Power down the system and remove the power cords from the rear of the power supply
modules, as described in section 3.1. Remove the chassis from the rack and seat it on a
work bench (safety area). Then open the chassis cover as described in section 3.2.
3.
Compare the mounting holes in the motherboard to those in the floor of the chassis. Add
or remove standoffs as needed. To do this, place a hexagonal standoff screw through
the bottom the chassis and secure the screw with a hexagon nut with the rounded side
up.
4. Lay the motherboard in the chassis, aligning it with the permanent and optional
standoffs.
5. Secure the motherboard to the chassis using the rounded, Phillips head screws. Do not
exceed eight pounds of torque when tightening the screws.
6. Secure the CPU(s), heatsinks, and other components to the motherboard as described
in the motherboard documentation.
7. Connect the cables between the motherboard, backplane, chassis, front panel, and
power supply modules, as needed. Also, the fans may be temporarily removed to allow
access to the backplane ports.
8. Replace the chassis cover, plug the power cords into the rear of the power supply
modules and power up the system.
