Power/Sleep/Message Waiting LED (MSGLED)
Connecting pins 2 and 4 to a single- or dual-color, front panel mounted LED
provides power on/off, sleep, and message waiting indication.
Power Switch (PWR)
Supporting the power on/off function requires connecting pins 6 and 8 to a
momentary-contact switch that is normally open. The switch should maintain
contact for at least 50 ms to signal the power supply to switch on or off. The
time requirement is due to internal debounce circuitry. After receiving a power
on/off signal, at least two seconds elapses before the power supply recog-nizes
another on/off signal.
