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.
PoE is on. The port LED is green only when the
switch port is providing power.
PoE is denied because providing power to the
powered device will exceed the switch power
capacity.
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.
PoE for the port is disabled. (PoE is enabled by
default.)
No link or port was administratively shut down.
Link present.
Activity. Interface is sending or receiving data.
Link fault. Error frames can affect connectivity,
and errors such as excessive collisions, cyclic
redundancy check (CRC) errors, and alignment
and jabber errors are monitored for a link-fault
indication.
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.
Port is blocked by STP and is sending and
receiving packets.
