Managing the Switch
A threshold value of -127 indicates that no thresholds are configured or applicable.
Note
You can display temperature readings for module temperature sensors by using the show environment
temperature command.
Enter the show environment temperature command.
Example:
switch# show environment temperature

◦ If the threshold is exceeded in a switching module, only that module is shut down.
◦ If the threshold is exceeded in an active supervisor module with HA-standby or standby
present, only that supervisor module is shut down and the standby supervisor module takes
over.
◦ If you do not have a standby supervisor module in your switch, you have up to 2 minutes to
decrease the temperature. During this interval, the software monitors the temperature every
5 seconds and continuously sends system messages as configured.
Tip We recommend that you install dual supervisor modules. If you are using a switch
without dual supervisor modules, we recommend that you immediately replace the fan
module if just one fan is not working.
