Dell PowerEdge VRTX - Manual (Page 37)

The switches map the mezzanine cards to the PCIe slots on the enclosure's system board. There are five PCIe low
profile slots on the system board and three full-height, full-length PCIe slots on the PCIe riser. All the PCIe slots can be
mapped to the PCIe mezzanine cards on the server modules to provide I/O expansion for the system:
PCIe mezzanine Fabric B and Fabric C cards on each server module are mapped to the PCIe switches which further map
to the PCIe slots and the Shared PERC slots on the enclosure's system board.
NOTE: For information on the specifications of the supported PCIe cards, see Technical Specifications .

Managing PCIe slots
You can do the following using the CMC web interface:
• View the status of both individual and all PCIe slots in the chassis.
• Assign PCIe slots to server modules.
