Replacing an I/O module

The I/O module is hot-swappable and therefore removal or replacement may be done by the user while the power supply is on.

Removing an I/O module

Important: Do not remove this module unless a replacement can be immediately added. The system must not be operated without all modules in place.

Grasp the module latch between the thumb and forefinger and squeeze them together to release the latch.
Pull the latch out to release the module from the enclosure as shown in the following figure.

Important: EMC precautions: if passive copper cables are connected, the cable must not have a connection to a common ground/earth point.

Examine for damage, closely inspect the interface connector. Do not install it if the pins are bent.
With the latches in the open position as shown in the figure below, slide the module into the enclosure until the latches engage.
