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. Use the
supported PCIe cards. For PCIe cards not listed in the
Checker, contact your local Huawei sales personnel.
Note 6: This table lists the default values of B/D/F. If thePCIe sockets are not fully
populated or a PCIe card with a PCI bridge is configured, the values of B/D/F may differ.
Note 7: For a server with NVMe PCIe SSDs, a 2-slot riser module must be installed on the
I/O module and an NVMe PCIe SSD adapter can be installed only in slot 7.
PCIe GPU Configuration Guidelines
A GPU must be installed on a PCIe riser module.

ESNs
An Equipment Serial Number (ESN) is a string that uniquely identifies a server. An ESN is
required when you apply for technical support from Huawei.

A 2-slot PCIe riser module supports one single-slot or dual-slot PCIe x16 GPU, which is
installed in slot 7.
A 3-slot PCIe riser module does not support any GPU.
