To calculate the total power consumption of the switch system in a certain configuration, fill out the table below in the following manner:

  1. In the Power column fill in the desired typical or maximum values.

  2. In the Quantity column, fill in the desired configuration. (Please note that the number of fans is not configurable and is always 1.)

  3. Get the total power per each FRU by multiplying values in adjusted columns in the same row.

  4. Get the total switch system power consumption system power by multiplying and summing up all the values.
