Upgrade from a Standard
Redundancy System
If you need to upgrade your standard redundancy system to an enhanced
redundancy system, complete this procedure.
Before You Begin
Before you begin upgrading from a standard redundancy system to an enhanced
redundancy system, consider these points:
• If the standard redundancy system uses a 1757-SRM redundancy module,
you must replace it with a 1756-RM redundancy module.
• You must upgrade all ControlNet or EtherNet/IP communication
modules.
• You must upgrade the firmware on all controllers.
• Depending on the enhanced redundancy system revision to which you are
upgrading, you may need to upgrade software.
