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.
l
Root Port (B/D/F) indicates the B/D/F of an internal PCIe root port of the processor.
l
Device (B/D/F) indicates the B/D/F (displayed on the OS) of an onboard or extended
PCIe device.
l
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.
l
The full-height half-length (FHHL) PCIe slots are backward compatible with half-
height half-length (HHHL) PCIe cards.
l
All slots support PCIe cards of up to 75 W. The power of a PCIe card varies depending
on its model.
l
The SP520, SP521, and SP522 do not support driveless server configuration. PXE boot
is recommended for driveless servers.
2.8 PSUs
l
The server supports one or two PSUs.
l
The server supports AC or DC PSUs.
l
The PSUs are hot-swappable.
l
The server supports two PSUs in 1+1 redundancy.
l
The same model of PSUs must be used in a server.
l
The PSUs are protected against short circuit. Double-pole fuse is provided for the PSUs
with dual input live wires.
l
Contact your local Huawei sales representative or use the
to determine the components to be used.
For a server configured with one or two 1500 W Platinum AC PSUs:
l
When the input voltage is from 100 V AC to 132 V AC, the output power drops to 1000 W.
l
Two 1500 W AC Platinum PSUs can serve as 1700 W PSUs.
