Alarms are not automatically deleted from the Alarms page. You must manually delete any alarm that you want to remove from the Alarms page. If you do not remove alarms that are no longer current, new, more recent minor alarms for a component will not be displayed on the Alarms page in place of previous, more major alarms for the same component.
When you are running the Enterprise Edition in conjunction with the System Edition and you have alarms that are passed from the System Edition to the Enterprise Edition, you must manually delete these alarms from the browser interfaces of both editions. If you do not do so, new lower-severity alarms for any component being monitored by the Enterprise Edition software will not display in place of previous higher-severity alarms for the same component.
