Procedure for Disabling Media Redundancy
When disabling Media Redundancy, the ring must be physically opened before storing configuration
to the modules. Here is the procedure to successfully disable Media Redundancy on a network.
1.
If the ring has no breaks in it, physically disconnect one (and only one) of the ring’s network
connections from the PNC
that’s currently the Media Redundancy Manager.
2. Change the configuration for the device that is the Media Redundancy Manager so that it will no
longer be the Media Redundancy Manager. If a GE Intelligent Platforms RX3i PNC is the Media
Redundancy Manager, use Proficy Machine Edition to disable the Media Redundancy role on
that PNC and then to download the hardware configuration. (If a third-party IO-controller is the
Media Redundancy Manager, the appropriate third-party configuration tool must be used
instead.)
