Replacement Considerations
Replace a Module in the
Secondary Chassis That Has the
Same Catalog Number and
Firmware Revision
These steps are used when performing a direct communication module
replacement, for example, when replacing a communication module in the
secondary chassis with a module that has the same:
• Catalog number
• Series
• Firmware (after updating the firmware, if necessary)
When you replace communication modules, make sure that the node address
(for ControlNet modules), rotary switches, and Port Configuration (for
EtherNet/IP modules) match the existing modules.
1. Using the Redundancy Module Configuration Tool (RMCT):
a. Set Auto-qualification
to Never.
b. Disqualify the redundant chassis pair (if not already disqualified).
2. Remove the module from the secondary chassis and replace it with the
new module.
3. If applicable, update the module firmware by using ControlFLASH™ or
ControlFLASH Plus™ software.
4. In the RMCT, from the Auto-Synchronization pull-down menu, choose
your preferred method.
5. If necessary, manually synchronize the chassis.
