3.8 Power-on behaviour
The power-on behaviour depends on the setting of the inhibit mode switch at the rear panel.
When the inhibit mode switch is set to "DEF" , the CMM controls the power supply inhibit, the
chassis can be powered by pushing the power button at the left front side.
When the inhibit mode switch is set to 'MAN' , the chassis boots when AC-power is applied,
as long as Pin 5 at the DSUB connector is not connected to GND.
3.9 Voltage monitoring
The female DSUB-9 connector allows remote monitoring of the system voltages.
