Brocade ICX7750: Stacking And Breakout Cables

I was reading this the other night, and wanted to pass this on to you engineers.  This is an important thing to know for the 7750 when you want to stack them together, IF you need a breakout cable (40gig to 4 10gig) for another purpose.  This below is from the FAQ for the 7750.

Q. Can splitter cables be used to split the Brocade ICX 7750 40 GbE ports into four 10 GbE ports?

A. Yes. The Brocade ICX 7750 supports the use of QSFP+ to 4x SFP+ splitter cables, but only when switches are running in a standalone switch configuration. Splitter cables cannot be used when Brocade ICX 7750 Switches are part of a stack (that is, running in a “stack member” configuration). Also, there are some restrictions concerning which QSFP ports can be split using these cables. Refer to the Brocade ICX 7750 product documentation for further details.
