Step 3: Power-Up and Power-Down
To Power Down the Chassis
For routine power-down or to cycle power to the chassis, momentarily
(< 5 seconds) press the chassis
ON/STANDBY
switch. The main chassis fans
gradually drop in speed to off, and the power supply unit (PSU) fans gradually
return to idle speed as the PSU cools. This is normal.
Once the chassis has cooled, you may isolate the chassis from AC power as
needed. 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 life
of the PSU. Use the front panel On/Standby switch to power down the unit, and
allow 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 fault
condition, the fault resets and the chassis goes to the OFF state.
