⚫
The B/D/F (Bus/Device/Function Number) is the default value when the server is fully
configured with PCIe cards. The value may differ if the server is not fully configured
with PCIe cards or if a PCIe card with a PCI bridge is configured.
⚫
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 (bus address displayed on the OS) of an onboard or
extended PCIe device.
⚫
The PCIe x16 slots are compatible with PCIe x16, 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 compatible with FHHL PCIe cards
and half-height half-length (HHHL) PCIe cards.
⚫
The maximum power supply of each PCIe slot is 75 W.
5.1.8 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.
⚫
PSUs of the same part number (P/N code) 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.
