Installing the Motherboard

Observe proper antistatic precautions when handling a new motherboard.

1. Remove the new motherboard from its protective antistatic packaging.

2. Position the motherboard so that the back panel I/O connectors (audio and USB ports) are on the upper left.

3. Place the motherboard in the chassis on top of the standoffs.

4. Slide the motherboard toward the chassis back panel until the I/O ports on the upper left side of the motherboard engage the opening in the chassis back panel and the screw holes in the motherboard align with the screw holes in the standoffs.

   The screw holes must align.

5. Secure the motherboard to the chassis using the nine Phillips-head screws (see Figure 3–36).
