FHHL
● The B/D/F (Bus/Device/Function Number) values are the default values when
the server is fully congured with PCIe devices. The values may vary if the
server is not fully congured with PCIe devices or if a PCIe card with a PCI
bridge is congured.
● 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.
● The SP520, SP521, and SP522 do not support driveless server
conguration.
PXE boot is recommended for driveless servers.
2.8 PSUs
● The server supports one or two PSUs.
● The server supports AC or DC PSUs.
● The PSUs are hot-swappable.
