Description
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.
Off: Port indicators do not show the stack
ID of the switch.
l Steady on:
The switch is not the master switch in
a stack.
– 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 Blinking:
The switch is the master switch in a
stack.
– 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.
