Некоторое PoE оборудование при включении кратковременно отключает питание, коммутатор думает что оборудование без PoE и отключает подачу напряжения на порт. В этом случае поможет установка параметра задержки отключения питания на портах:

Switch(config-if)#power inline max 15400
Max keyword specifies the maximum allowable Watt for the interface, the value is expressed in milliwatts, in this example the maximum Wattage is 15.4W or 15400mW
Manual power supply configuration
Switch(config-if)#power inline consumption default 5000
Meaning the interface will use the default 5W instead of auto-detection to determine the power needed to supply to PD.
Switch(config-if)#power inline consumption 5000
Manually set the power consumption on the specific interface instead of auto-detection to determine the power needed to supply to PD.
Since auto-detection is possible with CDP, it is recommended to disable CDP when using manual power supply configuration.
