Description
Enable thermal health check, and configure an action to be taken on detection of a thermal health event such as power leakage on PTX5K, MX10K, PTX10K and QFX10K devices. The thermal check feature monitors the PSM power output and FRU power consumption every minute. When the PSM power output exceeds the FRU power consumption by a default threshold for three consecutive iterations, it assumes a thermal health event and takes an action based on user configuration.
The default threshold for QFX10002 devices is 100 W and for other devices is 600 W.
The default action is set to none. It can be configured to shutdown all PSMs when thermal health check fails. The default shutdown timer is 900 seconds but can be configured. For example, the command provided below enables thermal health check, and shutdowns the system after 10 seconds of thermal health check failure:
set chassis thermal-health-check action-onfail auto-shutdown shutdown-timer 10 power-threshold 700
You can enable the PSM watchdog to shutdown the system in case a thermal health event causes Junos to go down. Please note that PEM firmware upgrade is required for the thermal health check and PSM watchdog feature.
You can enable the fet-failure-check option to monitor a failing power
supply due to a Field-effect Transistor (FET) failure and take corrective action. You
can choose to shutdown a reporting PSM if a redundant power supply is available, raise
an alarm and log the events when a risk of thermal event is
determined.
The fet-failure-check option is supported on MX10K and PTX10K
devices.
