For each alarm input, you can configure an open or closed circuit to trigger an alarm and configure the
severity of the alarm. A triggered alarm generates a system message. If you enter a descriptive name for
the alarm, that name is included in the system message. A triggered alarm also turns on the LED display
(the LED is normally off, meaning no alarm). See the Cisco IE 2000U Switch Hardware Installation
Guide for information about the LEDs.
The alarm trigger setting is open or closed. If not set, the alarm is triggered when the circuit closes.
• Open means that the normal condition has current flowing through the contact (normally closed
contact). The alarm is generated when the current stops flowing.
• Closed means that no current flows through the contact (normally open contact). The alarm is
generated when current does flow.
You can set the alarm severity to minor, major, or critical. The severity is included in the alarm message
and also sets the LED color when the alarm is triggered. The LED is amber for a minor alarm, red for a
major alarm, and blinking red for a critical alarm. If not set, the default alarm severity is minor.
