In this case, the following message displays: %Warning: Insufficient power to enable. POE oper-status set to OFF for port. • If the newly PoE or PoE+ -enabled port has a higher priority, the command is accepted and power is terminated on the lowest priority port in the power extender. If you add another PSU to the system later, both ports receive power. • If all the lower priority ports combined cannot meet the power requirements of the newly enabled port, the command is accepted but power on the lower priority ports is not terminated and power is not supplied to the port. The second result is true even if a powered device is not connected to the port. You can allocate power to a port, thus subtracting it from the power budget and making it unavailable to other ports, but that power is not consumed. Displaying Power Allocated to Power Devices To display PoE allocation to power devices by the port extender or port extender interface, use the following command. For more information on PoE power allocation, see Allocating PoE Power on an Interface. • Display PoE allocation on a port extender or port extender interface. Exec and EXEC Privilege mode show power inline {pe pe-id stack-unit unit-number | {interface interface} • pe pe-id - Enter the keyword pe and the port extender ID. The range is from 0 to 25. • stack-unit unit-number - Enter the keyword stack-unit and the stack unit number. The range is from 0 to 7. • interface interface - Enter the interface keyword and specify the PE Gigabit Ethernet interface using the keyword peGigE or peTenGigE. Specify a pe-id/unit/port for the interface.
