FAQ

Product-specific questions

Product-specific answers based on available technical information.

Is 1.5 Gbit/s the application data throughput?

No. NI specifies this as the serial link rate, not sustained application throughput.

Which system should be powered on first?

Power the secondary chassis before the primary host. Do not disconnect the MXI-3 cable while powered.

Can MXI-3 be directly mixed with MXI-Express x1?

No. NI identifies different board-to-board protocols and warns against mixing these interfaces.
