AMD XILINX VPK180 - Page 65

The VPK180 cooling fan connector is shown in the following gure. The VPK180 uses the
system controller to autonomously control the fan speed by controlling the pulse width
modulaon (PWM) signal to the fan. The fan rotates slowly (acouscally quiet) when ACAP U1 is
cool and rotates faster as the ACAP heats up (acouscally noisy).
The VPK180 board provides a fan controller bypass header J347 and J348 to permit control by
the Versal ACAP. See the Default Jumper and Switch Sengs for more details.

System Controller

The VPK180 board includes an onboard system controller. The system controller hosts a website
that allows for various controls over aspects of the evaluaon board. This web-based interface
enables the query and control of select programmable features such as clocks, FMC funconality,
and power system parameters. Users should not change the default system controller image as
that could potenally cause damage to the board if proper procedures are not followed. If this
image needs to be updated and for more informaon on the system controller web interface, see
the Versal Evaluaon Board System Controller Wiki.
The web applicaon is shown in the following gure.
