Port LED Color Meaning
Off PoE is off. If the powered device is receiving power from an AC power
source, the port LED is off even if the powered 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 amber exceed the switch power capacity.
Blinking amber PoE is off due to a fault.
Noncompliant cabling or powered devices can cause a PoE port fault.
Use only standard-compliant cabling to connect Cisco prestandard IP
Phones and wireless access points or IEEE 802.3af-compliant devices.
You must remove any cable or device that causes a PoE fault.
Amber PoE for the port is disabled. (PoE is enabled by default.)
Off No link or port was administratively shut down.
Green Link present.
Blinking green Activity. Interface is sending or receiving data.
Alternating Link fault. Error frames can affect connectivity, and errors such as
green-amber excessive collisions, cyclic redundancy check (CRC) errors, and
alignment and jabber errors are monitored for a link-fault indication.
Amber Port is blocked by Spanning Tree Protocol (STP) and is not forwarding
data.
After a port is reconfigured, the port LED can remain amber for up to
30 seconds as STP searches the switch for possible loops.
Blinking amber Port is blocked by STP and is sending and receiving packets.
