CAUTION

Risk of hardware damage

If you want to remove a card from an Application Module, you must perform the required software and hardware power-down processes. Hardware can be damaged if a component is reseated on the VME bus while the power is on, and the operating system can be corrupted if the power switch is turned off before the application performs a shutdown.
