XL710-QDA2 with Intel QSFP-40G-SR4 SFP

Hi All,

 

  We have "Intel Ethernet Converged Network Adapter XL710-QDA2".

 

  1) Configured in 2x40 mode

 

  2) The two ports on the board are connected back to back with below SFP:

       

        MACROREER

        40GBase-CU QSFP+ Cable 1m

       

      We are able to observe that the link status on both ports is UP. And, we are able to run tests between the ports.

     

  3) When we use the below Intel SFP's on both ports connected with MTP 24 fibre optical cable, the ports are not coming UP (Link status shows down)

 

        E40GQSFPSR

        QSFP-40G-SR4  16-26

        Class 1  21CFR1040.10

        LN#50 6/2007

        FTL410QE2C-IT

 

     Please help us in understanding why the ports are not coming up with the above mentioned Intel SPF's (point 3).

Is the optical cable we are using compatible with the SPF's or need to use some other optical cable or SFP to bring the ports UP?

Should we configure the board in any specific mode ?

 

Looking ahead for your response

Thanks in advance
