Spectrum integrated with UIM.
Spectrum alarms in UIM operator console alarm page cannot be set to invisible
When this is selected to invisible, the state does not change and some do not have the acknowledge option.
Release : OC 20.3.2
Component : UIM OPERATOR CONSOLE - ALARM VIEWER
For non clear-able alarms in spectrum this is working as designed i.e cannot clear them from UIM operator console
For clear-able spectrum alarms seen in UIM operator console alarm page upgrade to UIM 20.3.3 which has the fix included to resolve this .
