When either condition is met, the alarm LED turns red, and a syslog message and SNMP trap is
triggered.
Note
Check the software guide for the operating system you are running for information on alarm port
support.
Power Supply
The device can be configured to run dual power supplies. When set, the system expects to see both power
supplies functioning properly.
Note
Check the software guide for the operating system you are running for information on dual power supply
configuration and support.
When configured for dual power supply, and a failure occurs, the Alarm Out LED turns red. The alarm
relay is also energized. A syslog message is generated:
Syslog: %ASA-1-735006: Power Supply Unit Redundancy Lost
When configured for dual power supply, and a failure recovers, the Alarm Out LED turns off. A syslog
message is generated:
Syslog: %ASA-1-735005: Power Supply Unit Redundancy OK
Temperature Sensor
The operating system monitors the CPU temperature when it is running.
If the CPU temperature is in a critical condition (below -40°C or above 105°C), the Alarm Out LED turns
red.
When the CPU temperature returns to a normal condition, the Alarm Out LED turns off.
Note
The critical range of temperature is not configurable. It is hard coded as below -40°C or above 105°C.
