DE2 115 Error: Can't access JTAG chain Error: Operation failed

I have 2 DE2 115 boards. I am having problem with one of the board when configuring FPGA via JTAG. I can configure the on-board configuration device EPSC64 and then the net-list is downloaded to FPGA...

Extract from user manual, DE2-115

5. Turn the RUN/PROG switch (SW19) on the left edge of the DE2-115 board to RUN position; the PROG position is used only for the AS Mode programming.

Please help confirm your location for SW19 first.

Basically, configure FPGA is at the location of RUN, configure EPSC64 is at the point of PROG, FYI. Let me know if nothing changes.
