3. Connect cables from the motherboard to the drives.

5-6 Installing the Motherboard
Permanent and Optional Standoffs
Standoffs prevent short circuits by securing space between the motherboard and
the chassis surface. The SC847 chassis includes permanent standoffs in locations
used by most motherboards. These standoffs accept the rounded Phillips head
screws included in the SC847 accessories packaging.
Some motherboards require additional screws for heatsinks, general components
or non-standard security. Optional standoffs are included to 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).
Installing the Motherboard
1. Review your motherboard documentation. Become familiar with component
placement, requirements, precautions, and cable connections.
2. Open the chassis cover and remove the chassis from any power source.
3. As required by your motherboard, install standoffs in any areas that do not
have a permanent standoff. To do this:
3a. Place a hexagonal standoff screw through the bottom the motherboard
tray.
3b. Secure the screw with the hexagon nut (rounded side up).
