Back Panel Connectors
The motherboard external I/O connectors are attached to a metallic I/O shield. This
shield serves several purposes:
•
It protects the sensitive motherboard from any external EMC problems.
•
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 two serial ports, one parallel port, two RJ45 Local Area Network (LAN)
connections and two Universal Serial Bus ports.

NOTE: The mouse and keyboard CANNOT be plugged into either of the PS/2
connectors while the system is powered on. Power to the system must be turned off
before a keyboard or mouse is connected or disconnected.
