2.2.2.5.4

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.
