Hi,
The IS5023 is infiniband .
CX313A- is Ethernet, for full information see User Manual:
CX353A0- VPI which means will support both ethernet and infiniband, for full user manual:
Both of you cables are Ethernet cables, so this will not work
you can see cable information:

The IS5023 with your CX353A0 can work together , but you will need a different cable to support IB.
Please see cables list in the link above
