Displaying temperature warnings
If the temperature of a module exceeds the high temperature threshold for any of the fan speeds,
the system sends a warning message to the system log and an SNMP trap. (For more information
about the low and high temperature thresholds, refer to

The status can be one of the following:
•
OK – The fan is functioning properly and is keeping the temperature of each module within
an acceptable temperature range.
•
Failed – The fan is not functioning properly or the fan control module cannot control the
