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.
