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, two USB ports, one LAN Port and the audio
connectors.

Note: Power to the computer should be turned off before a keyboard or mouse is
connected or disconnected.
