@stephen Ages ago, a colleague of mine took a NAM server to Europe for installation
Prior to turning it on, he jokingly referred to the next step as the « smoke test »
In those days, the power supply had a switch for 110-220v (« convenienly » located at the back)and he had forgotten to activate 220v after arriving
It produced smoke and died.
We had to take a power supply for a similar model and expedite it over to Amsterdam
