		A green LED indicates connection status when a device is
		using a particular port.
		Port number 1 is also a power-forwarding port; it can be
		used with any standard networking device as well as to
		power a VoIP telephone on a network that uses IEEE
		802.3af-compatible Power Over Ethernet. An additional
		LED indicates when the port is forwarding power to a
		device connected to that port.
