Installing the Motherboard
I/O Shield
The I/O shield holds the motherboard ports in place. The I/O shield does not
require installation.
Permanent and Optional Standoffs
Standoffs prevent short circuits by securing space between the motherboard
and the chassis surface. The SC827 chassis includes permanent standoffs in
locations used by the motherboards. These standoffs accept the rounded Phillips
head screws included in the SC827 accessories packaging.
Some motherboards 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 a hexagon screw through the
bottom the chassis and secure the screw with the hexagonal nut (rounded side
up).
Depending upon the confi guration of the motherboard being used, it is also
possible that some of the optional standoffs which are pre-installed in the chassis,
may need to be removed.
