Introduction:

  • Power over Ethernet(PoE) describes any of several standardized or ad-hoc systems which pass electric power along with data on twisted pair Ethernet cabling. This allows a single cable to provide both data connection and electric power to devices such as wireless access points and IP cameras.
  • Power sourcing equipment (PSE) is a device such as a network Switch that provides (or sources) power on the Ethernet cable. The maximum allowed continuous output power per cable in IEEE 802.3af is 15.40 W. A later specification, IEEE 802.3at, offers 25.50 W. We can at most offer 32 W for AS4610-30P and AS4610-54P, 36 W for AG6248C.
  • A powered device (PD) is a device powered by a PSE and thus consumes energy. Examples include wireless access pointsIP Phones, and IP Cameras.

PoE function is applied to AS4610-30P and AS4610-54P in 2.7.2S1D and later versions, AG6248C in 2.9.2 and later versions.

Topology:

Here is a typical topology for PoE. The PDs are power devices connected to a PoE switch.

Configurations:

Enabling PoE on all ports is mandatory for other commands.
