1.3.3 Audible Alarms
The system comes with an audible alarm that is triggered when a
component fails or when the pre-configured temperature or voltage
thresholds are exceeded. Whenever you hear an audible alarm, it is
imperative that you determine the cause and rectify the problem
immediately.
Event notification messages indicate the completion configuration
tasks, status of components, or fatal errors. Events are always
accompanied by two (2) or three (3) successive and prolonged
beeps.
WARNING!
When an audible alarm is heard, system administrators should
rectify the cause of the alarm as soon as possible.
