Monitoring Airflow Temperatures and Handling Overheating
ExtremeWare provides a temperature logging function that allows the regular capturing of system
temperature to the system log. The
enable logging-temperature
command reports the internal
temperature (as reported in the temperature sensors on the active master MSM in the chassis) in the
system and logs temperature readings hourly in the system log. Additionally, general status is reported
through the
show switch
command. For more information about using these commands, see the
ExtremeWare Software User Guide and the ExtremeWare Software Command Reference Guide .
The active master MSM reports the temperature captured by ExtremeWare. While temperature sensors
are located on every module in the system, only the active MSM master controls the reporting for the
system. An overheating condition will be reported if a system temperature sensor detects a temperature
of 55° C or above.
NOTE
A module’s temperature sensor reading is no/- 5° C compared to the ambient temperature
measured around the equipment.
Automatic Shutdown in an Overheating Condition. The power supply controls the overheating
shutdown condition in the system. The power will shut down at approximately 85° C (+/- 5° C) as
reported on an independent temperature sensor within the power supply.
