2.8.2.4.4 Power Switch Connector [Red]
Pins 6 and 8 [Red] 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.
