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 a PS/2 keyboard/mouse combo port as well as one
serial port, four USB 2.0 ports, two USB 3.0 ports, two RJ-45 Ethernet Ports and the audio
connectors.
Note:
Power to the computer should be turned off before a keyboard or mouse is connected or
disconnected.
