Status of the power button

In the morning the company's one storage (double power, one Power switch is the following diagram state, another power switch is the opposite state), I think the following diagram state is to represent the "power off" (in fact, the following figure button is "power status"), so very "firmly" pressed the button below, so, the storage power off .... (Because another power supply is in a "power off state"). When the stored sound from the hum to mute, the cold sweat brush out of the moment, "I faint, I remember the wrong power status button ..." ”

Deliberately photographed, warning themselves.
