Dell emc s4148T-ON & Dell Force 10 MXL switch connectivity issue

Dear Communities

We recently purchased Dell EMC S4148T-ON and Dell force 10 MXL fabric switch. Both switch support 10 and 40 Gb port. When we tried to connect S4148T-ON to force 10 MXL switch using 40 Gb QSFP cable the port shows as down. We tired to connect 40 Gb port. 

We checked the cable . Its working.  When we loop switch particular switch port using QSFP cable the port shows up. We tried this on both switch. 

The problem will happen when we tried to connect s4148T-ON and force10 MXL.

 

Any idea. Any one help me for troubleshoot this issue.

Hi,

Is the firmware up to date? What kind of cable are you using? Are the transceivers the same type?

Thanks,
