5-4 Motherboard Installation
I/O Shield
The I/O shield holds the motherboard ports in place. The I/O shield does not re-
quire installation. However, you must confirm that the motherboard matches the
I/O shield.
Permanent and Optional Standoffs
Standoffs prevent short circuits by securing space between the motherboard and
the chassis surface. The SC809 chassis includes optional removable standoffs in
locations used by the motherboards. All of these standoffs are optional and are
removable.These standoffs accept the rounded Phillips head screws included in
the SC809 accessories packaging.
Some motherboard require additional screws for heatsinks, general components
and/or non-standard security. Optional standoffs are used for these motherboards.
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).
The SC809 chassis does not require optional standoffs.
