40 Gigabit Direct Attach Cable

Does anyone know if the Cisco QSFP-H40G-CU5M= (40 gigabit direct attach cable) will work between the MS425 switches and the MS355 switches? 

It's a 10x cost savings if they do.

I don't know the answer.

 

Some of the other Meraki switches only support TwinAx up to 3m.  So I would be more tempted to try:
QSFP-H40G-CU3M=

I am trying this same thing currently with QSFP-H40G-CU3M from MS355x2-48 to an MS425-32 and Cannot get this to work.

We are using some FS 40Gb DAC cables to connect MS355-24s to Force 10 blade switches: FS - 40GBASE-CR4: 10.3 Gbps (Part QSFP-PC02, Serial: F2033816787-1 ). We have also successfully used Dell 40Gb DAC cables.  We haven't tried with MS425s as we don't have any...
