2.4.3 Front Panel Switches & Indicators Headers

This header is used for connecting switches and LED indicators on the chassis front panel.

Watch the power LED pin position and orientation. The mark “+” align to the pin in the figure
below stands for positive polarity for the LED connection. Please pay attention to connect these
headers. A wrong orientation will only cause the LED not lighting, but a wrong connection of
the switches could cause system malfunction.
