An additional FPGA is used to fork one of the chip’s SPI-3 buses. The FPGA can be
configured by the NP to direct data flow either through the IXF1104 MAC on baseboard
and the crosspoint switch to the base channels and fabric channel 1,2 or through the
FIC card to additional fabric channels.
On the baseboard, there are connections between the FPGA and the IXF1104 MAC and
between the FPGA and the FIC that make it possible to work with the FIC card and the
IXF1104 MAC in 32-bit mode as well as 4x8-bit mode.
Fabric Interface Card
The Fabric Interface Card (FIC) is used to connect an IXB2850 board to the fabric
interface on the AdvancedTCA backplane. IXB2850 boards use a Gigabit Ethernet as
the switch fabric transport and conform fully to the PICMG 3.1 standard.
The FIC is based on the IXF1104 chip (Quad Gigabit Ethernet MAC) and for packet
processing is connected to the NP through the Media Access Module (see

plays in providing these paths. It also identifies specifically how the crosspoint switch
on the baseboard has been configured for the routing of data to the fabric interface
channels. The data paths to the base interface are shown for a configuration that does
not use the PrPMC and a configuration that uses the PrPMC.
