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
Computing Product Compatibility Checker. For details about other PCIe cards,
contact the local Huawei sales personnel.
Note 6: The table lists the default values of B/D/F. If PCIes are not in full
conguration or a PCIe card with a PCI bridge is congured, the values of B/D/F
may dier.
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
in slot 7.
