NOTE

The colors listed in Table 34 and Table 35 are suggested colors only. Actual LED colors are product- or customer-specific.

2.8.2.4.4Power 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.
