Configuring the NI-9154

You can connect the NI-9154 to a MXI-Express host system and configure the powerup options using a MXI-Express cable.

Connecting One or More NI-9154 Chassis to the MXI-Express Host System or a Target

Complete the following steps to connect one or more NI-9154 chassis to a MXI-Express host system or a target.
  1. Make sure the MXI-Express host system is set up and configured as described in the MXI-Express (x1) Series User Manual.
  2. If the MXI-Express host system is powered up, power it down.
  3. If the NI-9154 is powered up, power it down.
  4. Use a MXI-Express (x1) cable to connect the MXI-Express host system to the Upstream port of the first NI-9154 in the chain.
  5. Use a MXI-Express (x1) cable to connect the Downstream port of the first NI-9154 to the Upstream port of the next NI-9154 in the chain.
    Note The maximum number of NI-9154 chassis in a chain depends on the system configuration. For example, a PXI system with an NI PXI-8196 controller can support four chassis per chain. Different types of systems may support more or fewer chassis per chain. For more information about how different system configurations can affect the maximum number of chassis in a chain, go to ni.com/info and enter the Info Code 915xchain.
  6. Power up all of the connected NI-9154 chassis.
  7. Power up the MXI-Express host system.
    Note Refer to the MXI-Express (x1) Series User Manual for connectivity options and supported host devices.
    Caution All connected NI-9154 chassis must have power connected before the host system is powered up. The BIOS and OS of the host system must detect all bus segments on the chassis side in order to configure the PCI hierarchy. Powering connected chassis up or down while the host system is running can cause system hangs and data corruption.
    Caution Do not remove MXI-Express (x1) cables while power is connected. Doing so can cause hangs or application errors. If a cable becomes unplugged, plug it back in and reboot.

Configuring DIP Switches

All of the DIP switches are in the OFF position when the chassis is shipped from National Instruments.

NO FPGA APP Switch Push the NO FPGA APP switch to the ON position to prevent a LabVIEW FPGA application from loading at startup. The NO FPGA APP switch overrides the chassis powerup options described in Configuring the NI-9154. After startup you can download to the FPGA from software regardless of switch position.
USER FPGA Switches You can define the USER FPGA switches for your application. Use the LabVIEW FPGA Module and NI-RIO software to define the USER FPGA switches to meet the needs of your application. Refer to LabVIEW Fundamentals for information about programming these switches.
