Intel S845WD1-E - Server Board Motherboard, Product Manual

Installing the I/O Shield
CAUTION
Systems based on the S845WD1-E server board need the I/O shield properly
installed to pass emissions (EMI) certification testing and to meet Class B
emissions compliance levels. Without the I/O shield, or with an improperly
installed I/O shield, the server system will not meet Class B regulatory
compliance requirements.
The boxed server board comes with an I/O shield for a general purpose chassis. If installing this
board in an 1U chassis, obtain an I/O shield from the chassis vendor. When installed in the chassis,
the shield blocks radio frequency transmissions, protects internal components from dust and foreign
objects, and promotes correct airflow within the chassis.
Install the I/O shield before installing the server board in the chassis. Place the shield inside the
chassis and press the shield into place so that it fits tightly and securely. If the shield doesn’t fit,
obtain a proper-sized shield from the chassis supplier.
