Power On/Off Switch Sw15; Atx Power Supply Adapter Cable; Fpga_Prog_B Pushbutton Sw14 (Active-Low) - Xilinx KC705 User Manual

Do NOT plug a PC ATX power supply 6-pin connector into J49 on the KC705 board The ATX
CAUTION!
6-pin connector has a different pinout than J49. Connecting an ATX 6-pin connector into J49 will
damage the KC705 board and void the board warranty.
Figure 1-31 shows the power connector J49, power switch SW15 and indicator LED DS22.

The KC705 Evaluation Kit provides the adapter cable shown in
KC705 board from the ATX power supply 4-pin peripheral connector. The Xilinx part number
for this cable is 2600304, and is equivalent to Sourcegate Technologies part number
AZCBL-WH-1109-RA4. For information on ordering this cable, see

FPGA_PROG_B Pushbutton SW14 (Active-Low)

[Figure 1-2, callout 28]
Switch SW14 grounds the FPGA PROG_B pin when pressed. This action initiates an FPGA
reconfiguration. The FPGA_PROG_B signal is connected to FPGA U1 pin K10.
