Displaying the PoE Consumed by a Module
A Catalyst 4500 series switch can measure the actual PoE consumption for an 802.3af-compliant PoE
module. You can observe this consumption by using show power module and show power detail
commands. For all PoE calculations, presume that the PoE consumption on the WS-X4148-RJ45V
module equals its administrative PoE.
The 802.3af-compliant PoE modules can consume up to 20 W of PoE to power FPGAs and other
hardware components on the module. To ensure that the system has sufficient power for the PDs
connected to the switch, add at least 20 W to your PoE requirements for each 802.3af-compliant PoE
module.
The following example uses the show power module command to display the PoE consumption for an
802.3af-compliant module:

The Inline Power Oper column displays the amount of PoE consumed by the powered devices that are
attached to the module, in addition to the PoE consumed by the FPGAs and other hardware components
on the module.
The Inline Power Admin column displays only the amount of PoE allocated by the powered devices
attached to the module.
