Managing the Switch
• Major temperature threshold—When a major threshold is exceeded, a major alarm occurs and the
following actions occur:
A threshold value of –127 indicates that no thresholds are configured or applicable.
Note
This command reports on only software-controlled modules, such as supervisors, system controllers, line
Note
cards, fabric modules, fan trays, and power supplies. It does not report on modules that are not controlled
by software, such as blank modules installed in empty slots to control airflow.
Use the show environment temperature command to display the temperature readings for each of the
powered-up modules.

◦ Sends SNMP notifications (if configured)
◦ For sensors 1, 3, and 4 (outlet and onboard sensors), the following actions occur:
◦ Displays system messages.
◦ Sends Call Home alerts (if configured).
◦ Sends SNMP notifications (if configured).
◦ For sensor 2 (intake sensor), the following actions occur:
◦ 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.
We recommend that you install dual supervisor modules. If you are using a switch
Tip
without dual supervisor modules, we recommend that you immediately replace the fan
module if just one fan is not working.
