Issue
i2/b3 controller getting error " . . . OS update fail. Please retry" after OS upgrade is done. The Continuum Explorer shows exclamation mark (bang) on the controller icon. The control works normal, but it is confusing.
Environment
Infinet controllers (i2 controllers).
Bacnet controllers (b3 controllers).
NC2 (CX9680)
ACX5740
ACX5720
bCX4040
Cause
Controller OS upgrade has failed in the first try due to network issue or unstable system environment but succeeded on the second try or the next try.
Resolution
Bring up a listview of i2/b3 controllers. Find the one that displays the yellow exclamation mark (bang). Perform SetAttribute (right click on the controller and select "Set Attributes") for the ObjectStatus. Select the ObjectStatus and set the value to 0 .
