daisy chaining switches together via MPO

[robertkwild]

hi all,

going to be daisy chaining switches together, we got these QSFP modules

https://www.fs.com/uk/products/36157.html

so we need female to female MPO leads (as the module is male), just dont know if we need polarity A or B or key up or key down

thanks,

rob

        - In this case you will need Polarity B (to have flipped polarity) ,
