Displaying the PoE Consumed by a Module
The switch can measure the actual PoE consumption for an 802.3af-compliant PoE module, and it
displays the measured PoE in both the show power module and show power detail commands.
However, the switch cannot display the consumption of an individual interface on an 802.3af-compliant
PoE module, nor can it measure the actual PoE consumption for the WS-X4148-RJ45V module.
Therefore, for all PoE calculations, the PoE consumption on the WS-X4148-RJ45V module is presumed
to be equal to its administrative PoE.
