Add an Identical Chassis
After you have configured your primary chassis with the modules listed above,
add an identical chassis that contains the same modules with the same module-
placement.
For more information about chassis configuration, see the section titled
.
Upgrade to Enhanced
Redundancy Firmware
Once you have made the appropriate changes to your system configuration and
program, and have added the identical chassis, upgrade your system firmware.
For information about upgrading the redundant system firmware, see
Update Redundant Chassis Firmware on page 67
Update the Controller
Revision and Download the
Project
After you upgrade the firmware, use RSLogix 5000 software to access the
controller properties and update the controller revision to match the redundancy
firmware revision you are using.
Once you have updated the controller firmware revision and saved the changes,
download the updated program to the controller.
