1.4 Setting Jumpers
The Setup Jumper acts as "write protection" for the module’s flash memory. In
"write protected" mode, the Setup pins are not connected, and the module’s
firmware cannot be overwritten. Do not jumper the Setup pins together unless
you are directed to do so by ProSoft Technical Support.
The following illustration shows the MVI71-MNET jumper configuration.
Note: If you are installing the module in a remote rack, you may prefer to leave the Setup pins
jumpered. That way, you can update the module’s firmware without requiring physical access to
the module.
1.5 Install the Module in the Rack
If you have not already installed and configured your PLC processor and power
supply, please do so before installing the MVI71-MNET module. Refer to your
Rockwell Automation product documentation for installation instructions.
Warning: You must follow all safety instructions when installing this or any other electronic
devices. Failure to follow safety procedures could result in damage to hardware or data, or even
serious injury or death to personnel. Refer to the documentation for each device you plan to
connect to verify that suitable safety procedures are in place before installing or servicing the
device.
After you have checked the placement of the jumpers, insert MVI71-MNET into
the PLC™ chassis. Use the same technique recommended by Rockwell
Automation to remove and install PLC modules.
Warning: This module is not hot-swappable! Always remove power from the rack before
inserting or removing this module, or damage may result to the module, the processor, or other
connected devices.
