ESRP Environment Tracking
You can configure ESRP to track hardware
status. If a power supply fails, if the switch is overheating, or if a non-fully loaded
power supply is detected, the priority for the ESRP domain will change to the failover
settings.

Note
ExtremeXOS software determines the maximum available power required for the switch by calculating the number of power supplies and the power required by the installed modules. Enabling environmental tracking on the switch without enough power budget causes tracking to fail. In this case, the tracking failure occurs by design.To configure the failover priority for an ESRP domain:
