Installing the Motherboard
I/O Shield
The I/O shield (Figure 6-10) holds the motherboard ports in place. The I/O shield
does not require installation.
Permanent and Optional Standoffs
Standoffs prevent short circuits by creating space between the motherboard and
the chassis surface. The SC217 chassis includes permanent standoffs in locations
used by the motherboards. These standoffs accept the rounded Phillips head screws
included in the SC217 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 hexagonal screw through the bottom
the chassis and secure the screw with the hexagonal nut (rounded side up).
Depending upon the configuration 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.
Installing the Motherboard (Figure 6-11)
1. Review the documentation that came with your motherboard. Become
familiar with component placement, requirements, precautions, and cable
connections.
2. Disconnect the AC power cord from any power source.
3. Pull the motherboard node drawer out of the back of the chassis.
4. Remove the add-on card brackets:
a. Remove screw securing the add-on card bracket to the back of the node
drawer.
b. Lift the bracket out of the node drawer.
