The switch is detecting a powered device
(PD) on the port and is delivering power to
it.
The switch has shut down PoE+ on the port
because of a fault condition.
The switch is detecting a PD on the port, but
is not delivering power to it because the
maximum power budget has been reached.
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.
