Troubleshoot a Redundant System Chapter 9
Keeper Signature Mismatch
This example shows ControlNet modules in the redundant chassis that do not
have the same keeper signatures. With this anomaly, the ControlNet module
display indicates Keeper: Signature Mismatch.
This anomaly may result if a ControlNet module configured for the same node of
another network is used to replace a ControlNet module with the same node
address in the redundant chassis.

To correct this anomaly, do one of the following:
• Select the unconfigured module and click Update Keeper.
• Reschedule the ControlNet network.
