Fan Failures

When the system power is on, all three 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, the system controller shuts down the system.

If the system does shut down because the temperature exceeded the shutdown threshold, the system displays the following message on the console screen and in the environment display when the system restarts:

Queued messages:

%ENVM-1-SHUTDOWN: Environmental Monitor initiated shutdown

For complete descriptions and instructions for the environmental monitor commands, refer to the Configuration Fundamentals Configuration Guide and Configuration Fundamentals Command Reference publications, which are available on Cisco.com or the Documentation DVD.
