What is the difference between the DFM terms fault and alarm?

A fault is an event in which DFM determines a device is operating outside acceptable behavior—for example, a port is down that should be up, or a threshold has been exceeded that should not be exceeded. An alarm is a notification created by DFM to inform the user about the fault. DFM gathers information about the device and the fault, and then issues the alarm.
