Off PoE is off.

the port LED is off even if the powered device is connected to the
switch port.

providing power.

PoE is denied because providing power to the powered device will
exceed the 370 W switch power capacity.
Blinking amber PoE is off due to a fault.
Caution PoE faults are caused when noncompliant cabling or
powered devices are connected to a PoE port. Only
standard-compliant cabling can be used to connect Cisco
pre-standard IP Phones and wireless access points or
IEEE 802.3af-compliant devices to PoE ports. A cable or
device that causes a PoE fault must be removed from the
network.
Amber PoE for the port has been disabled.
Note PoE is enabled by default.
