✏ NOTE
To use the message waiting function, ACPI must be enabled in the operating system and a
message-capturing application must be invoked.
2.8.3.2.5 Power Switch Connector
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 D845HV/D845WN board.) At
least two seconds must pass before the power supply will recognize another on/off signal.
