● The B/D/F (Bus/Device/Function Number) values are the default values when
the server is fully configured with PCIe devices. The values may vary if the
server is not fully configured with PCIe devices or if a PCIe card with a PCI
bridge is configured.
● 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 3/4-length PCIe slots are backward compatible with FHHL or
HHHL PCIe cards.
● All slots support PCIe cards of up to 75 W. The power of a PCIe card varies
depending on its model.
5.7 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 Compatibility Checker
to determine the components to be used.
For a server configured with one or two 1500 W Platinum AC PSUs:
● When the input voltage is from 100 V AC to 132 V AC, the output power drops to 1000
W.
● Two 1500 W AC Platinum PSUs can serve as 1700 W PSUs.
