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?

POWER_OVER_BUDGET Alert on N7K

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.
