Factory Default Switch Settings
This section shows the factory switch settings for the Arria II GX FPGA development
board.
Figure 4–1 shows the switch locations and the default position of each switch.
To restore the switches to their factory default settings, perform the following steps:
1. Set DIP switch bank (SW3) to match Table 4–1 and Figure 4–1 .
