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 Installing the Module in the Rack
Make sure your ControlLogix processor and power supply are installed and
configured, before installing the MVI56E-MCM 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 the MVI56E-MCM
into the ControlLogix chassis. Use the same technique recommended by
Rockwell Automation to remove and install ControlLogix modules.
You can install or remove ControlLogix system components while chassis power
is applied and the system is operating. However, please note the following
warning.
Warning: When you insert or remove the module while backplane power is on, an electrical arc
can occur. An electrical arc can cause personal injury or property damage by sending an
erroneous signal to the system’s actuators. This can cause unintended machine motion or loss of
process control. Electrical arcs may also cause an explosion when they happen in a hazardous
environment. Verify that power is removed or the area is non-hazardous before proceeding.
Repeated electrical arcing causes excessive wear to contacts on both the module and its mating
connector. Worn contacts may create electrical resistance that can affect module operation.
1 Align the module with the top and bottom guides, and then slide it into the
rack until the module is firmly against the backplane connector.
