NOTE
l 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.
l 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.
l 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
Intelligent Computing Compatibility Checker .
For PCIe cards not listed by the Intelligent Computing Compatibility Checker, contact your local
Huawei sales personnel.
l When two 2.5-inch drives are installed in I/O module 1or 2, this module also supports a PCIe x16
riser card in slot 3 or 6.
l B/D/F indicates Bus/Device/Function Number.
l 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.
l The values of B/D/F listed in this table are default ones. If PCIe cards are not fully configured or a
PCIe card with a PCI bridge is configured, the values of B/D/F may differ.
l Atlas 300 accelerator cards are supported and dedicated riser cards are required. For details, see
Intelligent Computing Compatibility Checker .
2.11 Fan Modules
The fan speed can be adjusted. In normal cases, the fans run at the minimum speed. If the
server temperature increases, the speed will increase accordingly.
Figure 2-34 shows the fan modules.
