Connecting One or More NI 9155 Chassis to the MXI-Express Host System or a Target

Complete the following steps to connect one or more NI 9155 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 9155 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 9155 in the chain.
  5. Use a MXI-Express (x1) cable to connect the Downstream port of the first NI 9155 to the Upstream port of the next NI 9155 in the chain.
    Note The maximum number of NI 9155 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 9155 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 9155 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.
