Cooling Fan Connector
[Figure 1, callout 35]
The VEK280 cooling fan connector is shown in the following figure. The VEK280
uses the system controller to autonomously control the fan speed by controlling the
pulse width modulation (PWM) signal to the fan. The fan rotates slowly
(acoustically quiet) when the Versal device's U1 is cool and rotates faster as the
device heats up (acoustically noisy).
The VEK280 board provides a fan controller bypass header J347 and J348 to
permit control by the Versal device. See the Default Jumper and Switch Settings for
more details.
