DIP Switch M47
DIP switch M47 provides the ability to switch between using different PCI Express lanes for the ExpressCard slot and PCI Express Mini Card
socket. This is necessary because some congatec COM Express™ modules have onboard devices attached to PCI Express lane 5. The
default configuration is that the ExpressCard slot uses PCI Express lane 2 and the PCI Express Mini Card socket uses PCI Express lane 5.
In certain cases, it is necessary to use this DIP switch. For instance when dealing with some congatec COM Express™ modules that support
onboard Gigabit Ethernet implemented with PCI Express lane 5. This means that PCI Express lane 5 is not available externally. If the PCI
Express Mini Card socket must be used as well, then it is necessary to configure it to use PCI Express lane 2 instead of the default configuration,
which is PCI Express lane 5. Jumper X62 provides the ability to do this.

Note
In order to use both the ExpressCard slot and PCI Express Mini Card socket at the same time, PCI Express Lane 2 and 5 must be available.
