4.2.11 RESET push-button
The “RESET” signal is asserted during power-up, or by pressing the RESET push-
button switch (SW2).

The red LED (third LED down from the USB connector - JP4) on the SMT111 should
go off and illuminates every time you issue a hard reset (blue push-button - SW2).
It indicates that the Xilinx Spartan-3 FPGA firmware is loaded and running. You
should see that same result with the USB cable plugged in or not.
