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 Huawei Server Compatibility Checker to check
supported PCIe cards. For PCIe cards not listed in the Huawei Server Compatibility
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.
l A 2-slot PCIe riser module supports one single-slot or dual-slot PCIe x16 GPU, which is
installed in slot 7.
l A 3-slot PCIe riser module does not support any GPU.
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.
Figure 2-16 shows the ESN format by using the example 2102310QPD10F3001263.
