3.2. Default Switch and Jumper Settings

This topic shows you how to restore the default factory settings and explains their functions.

Figure 3. Default Switch Settings

1. Set DIP switch bank (SW2) to match the following table

Table 3.  SW2 DIP PCIe Switch Default Settings (Board Bottom)
Switch Board Label Function Default Position
1 x1 ON for PCIe x1 OFF
2 x4 ON for PCIe x4 OFF
3 x8 ON for PCIe x8 OFF
4 x16 ON for PCIe x16 ON

2. If all of the resistors are open, the FMC VCCIO value is 1.2 V. To change that value, add resistors as shown in the following table.

Table 4.  Default Resistor Settings for the FPGA Mezzanine (FMC) Ports (Board Bottom)
Board Reference Board Label Description
R460 1.35V 1.35V FMC VCCIO select
R464 1.5V 1.5V FMC VCCIO select
R468 1.8V 1.8V FMC VCCIO select
Note: A 0 Ohm resistor is installed by default

3. Set DIP switch bank (SW6) to match the following table.
