14 Keysight M9506A AXIe Chassis Startup GuideStep 3: Power-Up and Power-DownTo Power Down the ChassisFor routine power-down or to cycle power to the chassis, momentarily(< 5 seconds) press the chassis ON/STANDBY switch. The main chassis fansgradually drop in speed to off, and the power supply unit (PSU) fans graduallyreturn to idle speed as the PSU cools. This is normal.Once the chassis has cooled, you may isolate the chassis from AC power asneeded. This is usually done by opening the circuit breaker.For routine power-down, do not use the circuit breaker to turn the chassis off.Doing so interrupts power to the power supply fans, which may shorten the lifeof the PSU. Use the front panel On/Standby switch to power down the unit, andallow the PSU fans to return to idle before removing power from the chassis.Pressing and holding the power ON/STANDBY switch for greater than five (5)seconds shuts down the power supply immediately. If the chassis is in a faultcondition, the fault resets and the chassis goes to the OFF state.
