Table 1-9	Meaning of Switch LED Colors in Different Modes (continued)
Port Mode		Port LED Color	Meaning
PoE2		Off	PoE is off.
			If the device is receiving power from an AC power source, the port
			LED is off even if the device is connected to the switch port.
		Green	PoE is on. The port LED is green only when the switch port is
			providing power.
		Alternating	PoE is denied because providing power to the powered device will
		green and	exceed the switch power capacity.
		amber
		Blinking amber	PoE is off due to a fault or because it has exceeded a limit set in the
			switch software.
			Caution PoE faults are caused when noncompliant cabling or
				powered devices are connected to a PoE port. You can
				use only standard-compliant cabling to connect Cisco
				pre-standard IP Phones and wireless access points or
				IEEE 802.3af-compliant devices to PoE ports. You must
				remove from the network any cable or device that causes
				a PoE fault.
		Amber	PoE for the port has been disabled.
			Note PoE is enabled by default.

1.Only Catalyst 3750-E switches.
