icx7650 Stack Ports Down

[CiscotoRuckus]

Do icx7650's require license for stacking?  I can't seem to find the answer.  Using 40G QSFP Passive Copper cables.

Stacking does not need a specific license. You can find ICX7650 stacking details here:

https://docs.commscope.com/bundle/fastiron-08095-switchstackingguide/page/GUID-53B3025F-9BE9-4A78-B0...

Supported optic details can be found here:

Do you know exactly what SKU of cable you purchased? We will want to make sure it is supported for stacking (see page 5 of optics guide for 40Gb)
