LED	State	Description
PoE	Green	The switch is detecting a powered device
		(PD) on the port and is delivering power to
		it.
	Solid Amber	The switch has shutdown PoE+ on the port
		because of a fault condition.
	Flashing	The switch is detecting a PD on the port but
	Amber	is not delivering power to it because the
		maximum power budget has been reached.
	Off	This LED state can result from the following
		conditions:
		 The port is not connected to a PD.
		 The PD is powered off.
		 The port is disabled in the
		management software.
		 PoE is disabled on the port.
