You can use the Inhibit signal (active low) to power off the chassis. To
remotely power off the chassis, connect the Inhibit pin (pin 5) to a Logic
Ground pin (pins 1 or 9). As long as this connection exists, the chassis
remains off (standby). When you remove this connection, the chassis
powers on.
Note
For the Inhibit signal to control the On/Off (Standby) state of the chassis, the front
power switch must be in the On (recessed) position.
