Chassis SC822 User's Manual Installing the Motherboard Review the documentation that came with your motherboard. Become familiar with component placement, requirements, precautions, and cable connections. The motherboard should come with an I/O shield, holding the input and output ports. Permanent and Optional Standoffs Standoffs prevent short circuits by creating space between the motherboard and the chassis surface. The chassis includes permanent standoffs in locations used by most motherboards. These standoffs accept the rounded Phillips head screws included in the accessories package. Some motherboards require additional screws for heatsinks, general components or non- standard security.
Optional standoffs are included for these motherboards. To use an optional standoff, place the hexagonal nut with the rounded side up, in the holes provided on the floor of the chassis. Installing the Motherboard 1. Be sure the power cord is removed. 2. Install the I/O shield into the space provided at the rear of the chassis. 3. If necessary, remove the riser card bracket. 4. As required by your motherboard, install standoffs in any areas that do not have a permanent standoff and remove any standoffs that are not required by the motherboard. 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 which are included in the motherboard bag of the accessory box. Do not exceed eight inch-pounds of torque when securing the motherboard. 7. Secure the CPUs, heatsinks, and other components to the motherboard as described in the motherboard documentation. 8. Connect the cables between the motherboard, backplane, chassis, front panel, and power supply, as needed. The fans may be temporarily removed to allow access to the backplane ports and to allow for ease of installation. 36
