The datasheet for the X250e includes:
> EN 55024:A2-2003 Class A includes IEC 61000-4-2, 3, 4, 5, 6, 11
It also says
> IEC/EN 61000-4-2:2001 Electrostatic Discharge, 8kV Contact, 15 kV Air, Criteria A
So your switch should be hardened against static discharge.
Your older switch, well, I don't see its data sheet on line. But
maybe you've got one and can check.
If you're RMAing the switches, does that mean you have maintenance?
If yes, on a repeated problem like this you should be able to ask
their repair depot for some failure analysis.
