Displaying temperature warnings
If the temperature of a module exceeds the high temperature threshold for any of
the fan speeds, the system sends a message to the system log. This section
describes how to view the system log. If you have configured the system to use a
Syslog server, see the documentation for the server or receiver.
To display the system log, enter the following command at any CLI level:
# show log
