Configuring chassis ambient temperature to monitor power consumption of FPCs

You can set the ambient temperature of the chassis at 25° C or 40° C. On system initialization, the power manager reads the ambient temperature and allocates power to the FPCs according to the power budget policy at that temperature. If any FPC consumes more power than the configured value for more than 3 minutes, the PWR Range Overshoot alarm is raised for that FPC, and the power manager overrides the configured ambient temperature setting of that FPC and resets its ambient temperature to the next higher level and reallocates power according to the new temperature setting. All the overshooting FPCs remain in the dynamic ambient temperature mode until the next reboot, or until you override it with a CLI command. The power manager then resets the power budget of the FRUs, including the overshooting FPCs, according to the configured ambient temperature setting. To configure the ambient temperature, include the set chassis ambient-temperature statement at the [edit] hierarchy level.
