Configuration Switches PCI Express Link Width (DSW1)
The link width of the PCI Express interfaces attached to the PlusIO interface J2/P2 and the local
expansion connector P-PCIE is configurable by two DIP switches (DSW1) located on the backside of
the PC1-GROOVE. Note that changes in PCIe link width configuration are honoured by the
PC1-GROOVE not before a system reset was performed.

This setting is not useful and should not be used.
When a port is configured as single link, the PCIe switch may size down the link width to x2 or x1 by
auto-negotiation.
The following table shows the factory settings of DSW1 with different side boards mounted to the
