This section describes whether a PoE switch can supply power to IP cameras connected to the switch. For details about how to configure IP cameras, see the manual of the specific IP camera model.
Principles
Cause | Configuration to Be Performed on a PoE Switch |
|---|---|
The PD detection signature capacitance is larger than 0.15 uF. | Run the poe legacy enable command on the interfaces that connect the switch to PDs to enable PD compatibility check. |
The current of PDs cannot exceed 10 mA for more than 75 ms within every 325 ms after the PDs are powered on. | Run the poe power-on delay delay-time command on the interfaces that connect the switch to PDs to set the power-on delay. By default, the power-on delay of interfaces is 0. That is, power-on is not delayed. |
The current for a specific PD class is larger than 51 mA. | Run the poe force-power command on the interfaces that connect the switch to PDs to forcibly provide power to the PDs. |
