The illumination driver PCB contains the headers listed in
. These headers provide a protective
feedback loop between the active cooling fans and the power regulator. In the event that one of the fans is not
working or does not receive adequate input power, the feedback loop disables the power regulator and protects
the illumination driver circuitry. The headers can be removed to disable the fan feedback loops if fans are not
going to be used.
