Note 1: B/D/F stands for Bus/Device/Function Number.
Note 2: Root Port (B/D/F) indicates the bus number of a CPU internal PCIe root
port. Device (B/D/F) indicates the bus number (displayed on the OS) of an
onboard or external PCIe port.
Note 3: The PCIe slots that support full-height full-length PCIe cards are
backward compatible with full-height half-length or half-height half-length
PCIe cards.
Note 4: The PCIe slots with the bus width of PCIe x16 are backward compatible
with PCIe x8, PCIe x4, and PCIe x1 cards.
Note 5: All slots support PCIe cards of up to 75 W. The power of a PCIe card
varies depending on its model. For details about supported PCIe cards, use

contact the local Huawei sales personnel.
Note 6: The table lists the default values of B/D/F. If PCIes are not in full
configuration or a PCIe card with a PCI bridge is configured, the values of B/D/F
may differ.
Note 7: For a server with four NVMe PCIe SSDs, a 2-slot riser module must be
installed in I/O module 2 and an NVMe PCIe SSD adapter can be installed only
