Technical Reference 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. 2.2.2.5 Front Panel USB 2.0 Header Figure 12 is a connection diagram for the front panel USB 2.0 header. NOTE • The +5 V DC power on the USB header is fused. • Use only a front panel USB connector that conforms to the USB 2.0 specification for high-speed USB devices. Figure 11.
