- Set DIP switch bank (SW3) to match the following table.
Table 8. SW3 DIP PCIe Switch Default Settings (Board Top) Switch Board Label Function Default Position 1 x1 ON for PCIe x1 ON 2 x4 ON for PCIe x4 ON 3 x8 ON for PCIe x8 ON 4 — OFF for 1.35 V MEM_VDD power rail OFF - If all of the resistors are open, the FMCA and FMCB VCCIO value is 1.2 V. To change that value, add resistors as shown in the following table.
