Legacy Open Mesh: How Does Power over Ethernet (PoE) Work?



How does Power over Ethernet (PoE) work? 


  • Open Mesh Access Points


Power over Ethernet (PoE) works by sending power across unused Ethernet wire pairs in the CAT5 (or CAT6) cable, or via phantom power (802.3af).

PoE does not need a separate power cable to the access point from a power outlet. PoE is advantageous if you wish to place a unit in a spot where power is not readily available, and running a power cable is cumbersome.
