Display Mode Color Description
Yellow
l Steady on: The PoE function is
disabled on the port.

Green and
yellow
Blinking green and yellow alternately:
The port cannot provide power to a PD.
The possible reasons include:
l The power of the PD exceeds the
maximum power or power threshold
of the port.
l The total power consumption of PDs
has reached the maximum power of
the switch.
l The manual power management mode
is used and the port is not enabled to
provide power to the PD.
Stack Green
l Off: Port indicators do not show the
stack ID of the switch.
l If the indicator is steady on, the
switch is not a master switch:
– If the indicator of a port is steady
on, the number of this port is the
stack ID of the switch.
– If the first nine port indicators are
steady on, the stack ID of the
switch is 0.
l If the indicator is blinking, the switch
is a master switch:
– If the indicator of a port is
blinking, the number of this port is
the stack ID of the switch.
– If the first nine port indicators are
blinking, the stack ID of the switch
is 0.
