Configuring Geographical Redundancy
Prerequisites:
For the Geographical Redundancy to be set, two servers in the system are required.
In case of two Express Servers running as integrated, before proceeding, ensure that Link 2 is
disconnected.
Ensure all Express Servers in your system were configured in the DIMETRA Express Configuration
Wizard and have license files with the same profile. For more information, depending on your system,
see the DIMETRA Express Quick Start Guide or DIMETRA Express Standalone Quick Start Guide.
Procedure:
1 Log on the DIMETRA Express Network Manager of the Express Server to be the Primary server.
