To use the message waiting function, ACPI must be enabled in the operating system and a
message-capturing application must be invoked.
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 Desktop Board D865PERL.) At
least two seconds must pass before the power supply will recognize another on/off signal.
Figure 25 is a connection diagram for the front panel USB connectors.
