NOTICE
Note for bus modules with PCIe switch
As long as no modules are plugged into the PCIe slots behind a PCIe switch, the IRQs are
not used by the PCIe switch, but the display only shows that these IRQs would be used if
modules were plugged in.
The PCIe switch is displayed in Windows Device Management as "PCI standard PCI-to-
PCI bridge".

Bus board models

Riser cards are used as bus boards. These riser cards are used to a create spatial offset for
connections between the motherboard and the expansion cards. This positions the bus
board vertical and expansion cards parallel to the motherboard.
Depending on your device configuration, one of the following bus board models is mounted
in your device.
When plugging the PCI/PCIe cards observe the slot specification. The same number of PCIe
slots of the third generation (Gen. 3) are twice as powerful as slots of the second generation
(Gen. 2).
