RH2288H V3 server equipment PCIe slot layout

RH2288H V3 PCIe Device
I/O module 1 provides slots 1 to 3, and I/O module 2 provides slots 6 to 8.
I/O module 1 and 2 supports 2-slot PCIe riser module or 3-slot PCIe riser module, but three PCIe slots are always displayed on the panel.
*  If I/O module 1 provides two PCIe slots, slot 3 is unavailable.
*  If I/O module 2 provides two PCIe slots, slot 8 is unavailable.

Note 1: B/D/F, 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: The power supply capabilities of all slots support PCIe cards of 75 W. The power of a PCIe card depends on its model. For details about the supported PCIe cards, see Huawei Server Compatibility Checker. For PCIe cards out of the Huawei Server Compatibility Checker, contact your local Huawei sales personnel.
Note 6: Table 2-2 lists the default values of B/D/F. If CPUs 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 on I/O module 2 and an NVMe PCIe SSD adapter can be installed only in slot 7.
PCIe GPU Configuration Rules
A GPU must be installed on a PCIe riser module.
*  A 2-slot PCIe riser module supports a maximum of two single-slot PCIe x16 GPUs (bandwidth of one GPU: x8) or one dual-slot PCIe x16 GPU.
*  A 3-slot PCIe riser module does not support any GPU.
