NOTE: - A PCIe slot that supports a full-height full-length PCIe card is backward compatible with a full-height half-length or half-height half-length PCIe card. A PCIe slot that supports a full-height half-length PCIe card is backward compatible with a half-height half-length PCIe card.
- A PCIe slot that supports a PCIe x16 card is backward compatible with a PCIe x8, x4, or x2 card. A PCIe slot that supports a PCIe x8 card is backward compatible with a PCIe x4, or x2 card.
- 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 the Computing Product Compatibility Checker. For PCIe cards not listed by the Intelligent Computing Compatibility Checker, contact the local Huawei sales personnel to submit a compatibility test requirement.
- B/D/F indicates Bus/Device/Function Number.
- ROOT PORT (B/D/F) indicates the B/D/F of a CPU internal PCIe root port. Device (B/D/F) indicates the B/D/F (displayed on the OS) of an onboard or external PCIe port.
- This table lists the default B/D/F information. The values may be different if 1) The server is not fully configured with PCIe devices; 2) The PCIe cards in full configuration are of a different model or installed in different slots; 3) A PCIe card with a PCI bridge is configured.
