Environment  :  This article applies to Aruba AP-22X and IAP-22X Access Points.


PoE (Power over Ethernet) provides both data and power connections in one cable, so equipment doesn't require a separate cable for each need. It has two components in its implementation, Power Sourcing Equipment (PSE) and Powered Device (PD). 

Power sourcing equipment (PSE) is a device such as a switch that provides ("sources") power on the Ethernet cable. 
A Powered Device (PD) is a device powered by a PSE and thus consumes energy. Examples include wireless access points, IP Phones, and IP Cameras.

Different PoE capable devices have different power input requirements. Following table shows different PoE classes and the respective output power:




Here are the details of AP-22x Access Point behavior of with different classes of power input levels:

  • At normal condition AP22x uses :10W – 14W (all the 3 streams both the radio)


  • DC power:  Fully supported (all the 3 streams on both the radios)


  • 802.3at : Fully supported (all the 3 streams on both the radios)


  • 802.3af POE+ : Fully supported (all the 3 streams on both the radios)


  • 802.3af POE : Eth1 and USB will be disabled, 5GHz will be limited to 2x3 instead of 3x3, and 2GHz will be limited to 1x3 stream instead of 3x3.
