Alarm LED
Alarm LED
The ASA 5500-X series chassis perform autonomous environment monitoring to poll all external sensors
and monitor operating conditions. In the event of damage to certain internal components or surpassed
temperature thresholds, the system activates an alarm LED to notify you of a critical condition. For
example, the alarm LED is activated by firmware in the event of various critical over-voltage and
over-temperature conditions, as well as when the ASA has missing or unrecognized internal chip
components. When the alarm LED lights, you can find details about the system condition from the
system message that appears on the console or by entering the show environment or show controller
pci command.
