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 the Documentation CD-ROM or in print.
