Install the I/O Shield  NOTE An ATX 2.03-compliant I/O shield is provided with the server board. The shield is required by Electromagnetic Interference (EMI) regulations to minimizes EMI. If the shield does not fit the chassis, obtain a properly sized shield from the chassis supplier. The shield fits the rectangular opening near the power supply in the back of the chassis. The shield has cutouts that match the I/O ports. 1 Install the shield from inside the chassis. Orient the shield so that the cutouts align with the corresponding I/O connectors on the server board. Make sure the metal fingers are on the inside of the chassis. 2 Position one edge so that the dotted groove is outside the chassis wall, and the lip of the shield rests on the inner chassis wall. 3 Hold the shield in place, and push it into the opening until it is seated. Make sure the I/O shield snaps into place all the way around. B A OM10682 4 Place the I/O label on the I/O shield (on the outside of the chassis). The cut outs on the label are for the top serial port and the parallel port. 18 STL2 Server Board Quick Start Guide
