Product and Software: his article applies to all Aruba INDOOR APs, controllers and ArubaOS versions.


 The Aruba supports IEEE compliant 802.3af Power-over-Ethernet (PoE). There are two types of 802.3af power source equipment:


  • End-span are Ethernet switches with embedded Power over Ethernet technology, delivering data and power over the same wiring pairs - transmission pairs 1/2 and 3/6.
  • Mid-span are devices that are placed between legacy switches and the powered devices. It taps the unused wire pairs 4/5 and 7/8 to carry power and the other wire pairs to run data.

Before turning on power to an access point, the PoE switch will generate detection and classification phases to make sure the access points is PoEcompliant. 

All of Aruba's current APs are hardware set to return Class 0 during classification phase. The PoE switch uses this information for PoE power management.
