Fan Failures
When the system power is on, the Cisco uBR7225VXR router fans should be operational. The system
continues to operate if a fan fails; however, if the air temperature exceeds a defined threshold, the system
controller displays warning messages on the console terminal and, if the temperature exceeds the
shutdown threshold, it shuts down the system.
If the system does shut down because the temperature exceeded the shutdown threshold, the system
displays the following message on console screen and in environment display when the system restarts:
Queued messages:
%ENVM-1-SHUTDOWN: Environmental Monitor initiated shutdown
