PXIe-8240

I will be using a PXIe-8240 dual-port 40 Gigabit Ethernet peripheral module. 

 

The PXIe-8240 User Manual has a NOTE that states "Note For optimum performance, the chassis must have at minimum a Gen3 x8 peripheral slot (for example, the PXIe-1085)." 

 

The PXIe-8240 Specification manual states "Gen3 x8 PCI Express connection (maximum throughput is achievable with PXI Express Gen3 x8)." 

 

We have a PXIe-1085 chassis with a PXIe-8370 (MXI express Gen 3) but it is being used on another project. 

 

We have a PXIe-1084 chassis with a PXIe-8381 (MXI express Gen 2 x8) that is not being used. 

 

Will the PXIe-8240 ethernet module work with a PXIe-1084 chassis with a PXIe-8381 (MXI express Gen 2 x8)? 

 

Will the PXIe-1084 chassis with a PXIe-8381 (MXI express Gen 2 x8) work with a lower speed (minimum throughput) of the PXIe-8240?

 

I don't need to run at optimum performance or maximum throughput. 

I want to know if the PXIe-8240 will work with a slower chassis with (MXI express Gen 2 x8) at slower throughput. 

 

Thank you

Yes, it should identify and work, but will be limited in throughput by the slower PCIe generation/lane counts.
