electrical load of cisco switches

[jendoubi Abdelbasset]

hello,

how i can calculate the electrical load of cisco switches ??

There is not really a way to "calculate" it. But the data sheets typically provide some information on the power consumption. For example for the Catalyst 9200 it's in Table 16 of the data sheet:

As Karsten already described, device (and card/module) datasheets usually provide power consumption figures, but know these are a bit inexact in the "real world", as device's power consumption will vary based on how it's being used. The datasheet numbers, though, probably lean more toward worst case.

Some switches will also show current power loading using the correct "show" command.

Another option would be to use some 3rd party power monitoring device, and running the device under expected load.
