Back Panel Connectors
The motherboard external IO connectors are attached to a metallic I/O shield. This
shield serves several purposes:
It protects the sensitive motherboard from any external EMC interference.
It stops the computer from interfering with other electrical devices.
It allows the motherboard to be easily upgraded in the future without having to
resort to buying a whole new case. Simply change the I/O shield to match the
motherboard.
The I/O shield provides external access to PS/2 keyboard and mouse connectors as
well as one serial port, one parallel port, four USB ports, one LAN Port and the audio
connectors.
