2.2.2.4.4 Power Switch Header
Pins 6 and 8 can be connected to a front panel momentary-contact power switch. The
switch must pull the SW_ON# pin to ground for at least 50 ms to signal the power
supply to switch on or off. (The time requirement is due to internal debounce circuitry
on the board.) At least two seconds must pass before the power supply will recognize
another on/off signal.
