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.
