Installing MXI Cables

Note You must use an RTM-3661 module with the ATCA-3671 module for host access to the FPGAs from LabVIEW. Direct host access is not supported for other RTMs.
  1. Connect one end of a Gen3 MXI cable to the corresponding port on the installed RTM-3661 module for each FPGA.
    1. Start with Port 1 when you connect the MXI card. Connect MXI Port 1 to the first PCIe port (0, 1, ...) on the RTM that corresponds to the first FPGA (A, B, C, or D) to which you will connect.
    2. Continue making connections in ascending order until you have made all necessary connections.
      For example, if you require two connections to FPGA B and one connection to FPGA C, first connect Port 1 on the MXI Card to PCIe B, Port 0 on the RTM. Then connect Port 2 on the MXI Card to PCIe B, Port 1 on the RTM. Finally, connect Port 3 on the MXI Card to PCIe C, Port 0 on the RTM.
  2. Connect the other end of the Gen3 MXI cable to a compatible Gen3 MXI PCI Express or PXI Express adapter on the host computer or PXI chassis.

    Refer to the Gen3 MXI documentation for any additional connectivity requirements.

  3. Power on the ATCA-3671 after all desired MXI connections are made between the RTM-3661 and host-side adapters.
  4. Wait 90 seconds and then power on the host computer or PXI controller.

    Some host-side MXI adapters, such as the PXIe-8394 module, have a link status LED to indicate that a PCI Express link has been established successfully between the target and host. Refer to the Gen3 MXI x8 documentation to verify whether a link status LED may be used to verify the presence of a host link as the computer starts.
