Configuration Limitations for PoE

Configuration Limitations for PoE

Feature Limitations

  • When the PoE power supply standard of an AP changes from 802.3af to 802.3at or from 802.3at to 802.3bt, the AP will not restart. When the PoE power supply standard of an AP changes from 802.3bt to 802.3at or from 802.3at to 802.3af, the AP may restart.
  • When an 802.3at AP that does not support hardware detection is connected to a switch whose power supply mode is 802.3af, the AP restarts repeatedly if the LLDP function is disabled on the switch.
  • When an 802.3at AP that supports hardware detection is connected to a Cisco switch whose power supply mode is 802.3af, the AP restarts repeatedly if the LLDP function is disabled on the switch.
  • The AP8050DN and AP8150DN cannot be connected to a switch whose power supply mode is 802.3af because the APs will restart repeatedly after their power consumption exceeds the power allowed by 802.3af. When the AP8050DN and AP8150DN are connected to a Cisco switch whose power supply mode is 802.3at, the APs will restart repeatedly after their power consumption exceeds the power allowed by 802.3at if the LLDP function is disabled on the switch.
  • An 802.3bt AP cannot be connected to an 802.3af switch or a Cisco's 802.3at switch.
  • If the interval for sending LLDP packets is longer than 90 seconds, LLDP negotiation may time out, causing the device to incorrectly consider that the LLDP function is not supported or disabled.

PoE Functions Provided by the Device

  • The device supports power supply capability negotiation using Link Layer Discovery Protocol (LLDP).
  • PoE power supply is independent of the system power supply. You can configure maximum power, alarm threshold, and reserved PoE to the total power supply.
  • The device supports automatic, manual, and forcible power-on and power-off mode.
  • The device can detect PDs that are compliant with 802.3af or 802.3at and provides power for these PDs.
  • The device can be configured with the power-off time range to facilitate PD management.
  • PoE OUT is supported only by the AP8082DN, AP8182DN, AP4050DN-E, AP4050DN-HD, AP7050DN-E, R250D-E, AP2050DN-E, AP2051DN-E, R251D-E, AD9431DN-24X, AD9430DN-24, and AD9430DN-12.
