6.2Hot Swapping An Ethernet Module

You may replace your Ethernet web embedded server module while the controller is running. However, you should first make sure that the IP network address of the replacement module will be unique on your network.

The new Ethernet module will inherit any configuration changes you had made. If the original Ethernet module was given a user-configured address, the new module will assume that address. If you will be using the default address, check with your system administrator to ensure that address is not already in use on your network.

To hot swap the module, simply disconnect the cable and remove the old module from the backplane. Then insert the new module in the slot and reconnect the cable.

If you are replacing the module because it failed, be aware that you may have lost several transactions. These transactions are not captured in memory and cannot be recovered by the new module.
