
The bus, device, and function number (B/D/F) in the table is the default value when the
PCIe cards are fully configured, which may vary if the PCIe cards are not fully configured or
PCIe cards with PCI bridge are installed.

Root Port (B/D/F): the B/D/F of the PCIe root node of the processor.

Device (B/D/F): the B/D/F of the onboard or expanded PCIe device viewed in the OS, that
is, the bus address.

A PCIe x16 slot is compatible with a PCIe card with the bus bandwidth of x16, x8, x4, or x1.

It is not upward compatible, that is, the bandwidth of the PCIe slot should be larger than
that of the inserted PCIe card.

A FHFL PCIe slot is compatible with FHFL PCIe card, FHHL PCIe card, and HHHL PCIe
card.

A FHHL PCIe slot is compatible with FHHL PCIe card and HHHL PCIe card.

The power supply capacity of each PCIe slot is up to 75 W.
