Configuring PoE Power-on and Power-off Management

Procedure

• Set the power priority of PoE interfaces on the AP.

  You can configure power priorities for PoE interfaces: critical, high, and low. When the available power is insufficient, the AP provides power first for the PDs connected to high-priority interfaces.

  The priorities in descending order are critical, high, and low.

  1. Run the system-view command to enter the system view.
  2. Run the wlan command to enter the WLAN view.
  3. Run the port-link-profile name profile-name command to create an AP wired port link profile and enter the profile view.

     By default, the system provides the AP wired port link profile default.

  4. Run the poe priority { critical | high | low} command to set the power priority of PoE interfaces on the AP.

     By default, the power supply priority of an interface is low.

• Set the power-off time range of a PoE interface.

  PDs connected to an interface do not keep working. You can set the power-off time range of a PoE interface so that it can automatically power off when it is idle to save energy.

  1. Run the system-view command to enter the system view.
  2. Run the time-range time-name { start-time to end-time { days } &<1-7> | from time1 date1 [ to time2 date2 ] } command to define a power-off time range of PoE.
  3. Run the wlan command to enter the WLAN view.
  4. Run the port-link-profile name profile-name command to create an AP wired port link profile and enter the profile view.

     By default, the system provides the AP wired port link profile default.

• Configure the device to be compatible with non-standard PDs

  When a non-standard PD is connected to the AP, the AP cannot detect the proper resistance and cannot identify the PD. When compatibility check is enabled, the AP can detect and provide power for the PD that does not comply with the IEEE 802.3af or IEEE 802.3at standard.

  1. Run the system-view command to enter the system view.
  2. Run the wlan command to enter the WLAN view.
  3. Run the port-link-profile name profile-name command to create an AP wired port link profile and enter the profile view.

     By default, the system provides the AP wired port link profile default.

  4. Run the poe legacy enable command to enable PD compatibility check on the AP.

     By default, an AP does not check compatibility of the connected PDs.

• Configure the PoE standard type.

  The AP that supports IEEE 802.3at provides a maximum power of 30 W, and the AP that supports IEEE 802.3af provides a maximum power of 15.4 W. The former AP provides higher current than the latter AP when they power on PDs.

  Some non-standard PDs cannot be powered on in high current. To power on these PDs, configure the AP to provide power with low current in conformance to IEEE 802.3af.

  1. Run the system-view command to enter the system view.
  2. Run the wlan command to enter the WLAN view.
  3. Run the ap-system-profile name profile-name command to create an AP system profile and enter the profile view.

     By default, the system provides the AP system profile default.

  4. Run the poe af-inrush enable command to configure the AP to provide PoE power in compliance with IEEE 802.3af.

     By default, an AP provides PoE power in compliance with IEEE 802.3at.

     This function is supported only by the AP4050DN-E, AP4050DN-HD, AP7050DN-E, AP8082DN, AP8182DN, AP2050DN-E, AP2051DN-E, R250D-E, R251D-E, AD9431DN-24X, AD9430DN-24, and AD9430DN-12.

     

     After running the poe af-inrush enable command, remove the non-IEEE 802.3at PDs and then install them so that the PDs can be powered on.

• Power on PDs on an interface forcibly.

  After this function is configured, an interface forcibly powers on the connected PD even if the PSE cannot identify the PD. Before powering on the interface, ensure that the system power is sufficient.

  1. Run the system-view command to enter the system view.
  2. Run the wlan command to enter the WLAN view.
  3. Run the port-link-profile name profile-name command to create an AP wired port link profile and enter the profile view.

     By default, the system provides the AP wired port link profile default.

  4. Run the poe force-power command to enable PoE power supply on the AP's interfaces.

     By default, forcible PoE power supply is disabled on an interface.
