I recently bought a single rack server, but I often get shocked when I touch the full-metal case. It seems to take 20-30 minutes to "charge" between shocks, but I'm not enthusiastic about testing that statistic further. It's connected to a properly grounded surge protector and no other objects touch it besides the wooden desk it lays on, which in turn stands on a tile floor. I assume the shock is static as I can safely touch the case after each shock. If I'm in relatively consistent contact with the case, no static charge builds. Only when it sits idle for an extended period of time do I experience these shocks. Put simply:
- Metal case causes regular static shocks when left untouched long enough
- Power Setup: server → surge protector → grounded wall outlet (indicated by the surge protector)
I know nothing about electricity, so can someone please explain possible sources of this static and potential fixes? Might my surge protector or house wiring be faulty, or is this an unavoidable feature, however unlikely? Thank you for reading.
