Usage Guidelines
If a powered device i s connected to an interface with external power, the switch does not recognize the
powered device. The Device column in the output of the show power inline command displays as
unknown.
If your port is not capable of supporting Power over Ethernet, you will receive the following error
message:
Power over Ethernet not supported on interface Admin
The show power in-line interface | module command displays the amount of power used to operate a
Cisco 7960 IP Phone. To view the amount of power requested, use the show cdp neighbors command.
Because of the PoE consumed by FPGAs and other hardware components on the module the operating
PoE consumption for an 802.3af-compliant module can be nonzero, even when there are no powered
devices attached to the module. The operating PoE can vary by as much as 20 watts because of
fluctuations in the PoE consumed by the hardware components.
