Understanding the ICU
The ICU window allows access to all ICU functionality, including cluster
configuration. The ICU also displays a list of controllers connected to the
subnet and the configuration information as it is stored on each controller.
Displaying and Updating Cluster Information
At startup, the ICU broadcasts a query across the subnet to controllers,
requesting their configuration information. Controllers that are powered on
respond to the query by sending their information to the ICU, which then
displays the information in the ICU window.
The ICU window is updated whenever a controller connection status changes.
Refresh the window for the latest connection information. See “Refreshing
Controller Information” on page 5-13 for additional information.
