● The B/D/F (Bus/Device/Function Number) values are the default values when
the server is fully congured with PCIe devices. The values may vary if the
server is not fully congured with PCIe devices or if a PCIe card with a PCI
bridge is congured.
● Root Port (B/D/F) indicates the B/D/F of an internal PCIe root port of the
processor.
● Device (B/D/F) indicates the B/D/F (displayed on the OS) of an onboard or
extended PCIe device.
● The PCIe x16 slots are backward compatible with PCIe x8, PCIe x4, and PCIe
x1 cards. The PCIe cards are not forward compatible. That is, the PCIe slot
width cannot be smaller than the PCIe card link width.
● The full-height half-length (FHHL) PCIe slots are backward compatible with
half-height half-length (HHHL) PCIe cards.
● All slots support PCIe cards of up to 75 W. The power of a PCIe card varies
depending on its model.
5.8 PSUs
● The server supports one or two PSUs.
● The server supports AC or DC PSUs.
● The PSUs are hot-swappable.
● The server supports two PSUs in 1+1 redundancy.
● The same model of PSUs must be used in a server.
● The PSUs are protected against short circuit. Double-pole fuse is provided for
the PSUs with dual input live wires.
● Contact your local Huawei sales representative or use the Computing
Product Compatibility Checker to determine the components to be used.
NO TE
● When one or two 900 W AC Titanium PSUs are congured and the input voltage ranges
from 100 V AC to 127 V AC, the output power decreases to 550 W.
● When one or two 1500 W AC Platinum PSUs are congured:
● When the input voltage ranges from 100 V AC to 127 V AC, the output power
decreases to 1000 W.
● Two 1500 W AC Platinum PSUs can serve as 1700 W PSUs.
