2 Installing the I/O Shield
The board comes with an I/O shield. When installed in the chassis, the shield
blocks radio frequency transmissions, necessary to pass emissions (EMI)
certification testing, protects internal components from dust and foreign objects,
and promotes correct airflow within the chassis.
Install the I/O shield before installing the board in the chassis. Place the shield
inside the chassis as shown in the following figure. Press the shield into place
so that it fits tightly and securely. If the shield doesn't fit, obtain a properly-
sized shield from the chassis supplier.
