Customers may have various operational reasons in PROD environments for wanting to lower the severity of an alarm or alarms related to alarm management processes.You may be sending major/critical alarms to your help desk system as P1 Critical Events that page your on call personnel. For example, you may be getting sporadic major alarms from controllers that say "Failed to send set_hub to spooler (communication error)". This is a known problem that's fixed in robot version 5.52 and it generally is not a serious condition and it seems to eventually resolve itself in most cases. You may not want to ignore the alarms in case there is a real problem so as an alternative, you want them to show up in the alarm viewer as warnings so you can see them but they don't wake people up in the middle of the night.
Then use the nas Status window and rt-click and send a test alarm with Critical severity (level 5) and message like Test message from stevedAnd you will see in the alarm sub-console window the alarm will automatically be changed to a major severity. (level 4).
