POWER_OVER_BUDGET Alert on N7K

[Mohammad Tbaili]

I am getting the following error on N7K

%PLATFORM-1-PFM_ALERT: POWER_OVER_BUDGET: Power has dropped. Existing power is insufficient

What does it mean?

As a starting point enter all the blades you have installed in your switch into the power calculator below:

The power supply you have installed in the switch may not have sufficient capacity to support the number and types of blades installed.

Don't forget to rate all helpful posts.

Hi ,

The strange thing is that we have another N7k which has more blades than this N7k and it is not showing any alerts !!!!
