(Optional) Configuring the PoE Power Supply Delay

(Optional) Configuring the PoE Power Supply Delay


The maintain current of the used PD is insufficient at the power-on moment, so the PoE switch considers that the PD has been disconnected and powers it off. IEEE standards require that a PD must maintain a current value of more than 10 mA for at least 75 ms in each 325 ms duration. Otherwise, the PoE switch considers that the PD has left and powers off the PD.

To enable the PoE switch to power these non-standard PDs, set the PoE power supply delay on the appropriate interfaces of the switch so that the switch detects the maintain power of the PDs after the specified delay.


  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Run poe power-on delay

    The PoE power supply delay is configured for the interface.

    By default, the PoE power supply delay is 0. That is, the PoE power supply is not delayed.
