Alerts are retained on the alarms page until the system component returns to its fully functioning state. Restoring a
component’s function might be accomplished by restarting the system, running a BIT test, or the component may
require maintenance. The software is capable of storing up to 16 alert messages only. Additional alerts are added
by dropping the previous alerts with the oldest time stamp.
