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:

int range fa0/2 - 24
power inline delay shutdown 10 initial 20

Class selector
Class 0 (default) 15.4W (PSE), 0.44 ~ 12.95W (PD)
Class 1 (very low power) 4.0W(PSE), 0.44 ~ 3.84W(PD)
Class 2 (low power) 7.0W(PSE), 3.84 ~ 6.49W (PD)
Class 3 (Mid power) 15.4W(PSE), 6.49 ~ 12.95W(PD)
Class 4 (High power) Reserved.

установим лимит мощности на порт мл W

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.
