The BlueField BF1600 Controller Card supports PCI Express Gen 3.0 (1.1 and 2.0 compatible) through two on-card x8 CABLINE-CA II PLUS connectors that
together provide an additional x16 PCIe interface. The belly to belly CABLINE-CA II PLUS connectors are located on the component and print side of the
card and they are connected to the BlueField SoC. The PCIe TX from the system platform (Transmit signals) are connected through the component side
CABLINE-CA II PLUS connector, while the PCIe RX from the system platform (Receiving signals) are connected through the print side of the CABLINE-CA II
PLUS connector. The connectivity to the NVMe SSDs is allowed through the two CABLINE-CA II PLUS harnesses that are combined to a second x16 PCIe Edge
connector mounted on the Auxiliary card.
NCSI Management Interface
The Network Controller Sideband Interface (NCSI) enables the connection of a Baseboard Management Controller (BMC) to a card for the purpose of
enabling out-of-band remote manageability. NCSI over the RMII interface is routed through the RMII connector with a flat cable.
