[Asservic]

It have been a week since I am trying to stack a SG350x-48p with a SG500-52p but no succes.

Is it even possible ?

Hi Asservic, 

That implementation is not possible. Stack units must be from the same family to form a stack (SG350X/SG350XG or SG550X/SG550XG). Please refer to Stack Unit Mode section in the admin guide  https://www.cisco.com/c/dam/en/us/td/docs/switches/lan/csbms/350xg/admin_guide/AG_Tesla_350_550.pdf (page 130)

Thanks,

Martin
