Installation Step 3: Installing the Motherboard
I/O Shield
The I/O shield holds the motherboard ports in place. Install the I/O shield before
you install the motherboard.
To install the I/O shield:
1. Review the documentation that came with your motherboard. Become familiar
with component placement, requirements, and precautions.
2. Open the chassis cover.
3. With the illustrations facing the outside of the chassis, place the shield into the
space provided.
4. Once installed, the motherboard will hold the I/O shield in place.
Permanent and Optional Standoffs
Standoffs prevent short circuits by securing space between the motherboard and
the chassis surface. The SC933 chassis includes permanent standoffs in locations
used by most motherboards. These standoffs accept the rounded Phillips head
screws included in the SC933 accessories packaging.
Some motherboards require additional screws for heatsinks, general components
and/or non-standard security. Optional standoffs are included to these mother-
boards. To use an optional standoff, you must place the hexagonal screw through
the bottom the chassis and secure the screw with the hexagon nut (rounded side
up).
