4 Execute the activate
power inline operation
command, and then use the
show power inline
operation command to check
the information displayed for
Status for the target port.
 off displayed:
Make sure a power-receiving device is connected.
 on displayed:
Continue using the switch.
 faulty displayed:
There might be a problem with the power-receiving device or a
connection cable. Go to No. 6.
5 Execute the activate
power inline operation
command, and then use the
show power inline
operation command to check
the information displayed for
Status for the target port.
 off displayed:
Make sure a power-receiving device is connected.
 on displayed:
Continue using the switch.
6 Use the show logging
operation command to check
whether a POE log is being
recorded.
 When 0/x Supplying power was stopped by the overload
detection. is displayed:
Power cannot be supplied because an overload was detected.
Check the power-receiving device or connection cables. If the
problem cannot be corrected, check the cable length and cable
type in the Hardware Instruction Manual, and replace the cables.
If devices to which PoE power can be supplied are connected, use
the power inline configuration command to disable PoE on the
port.
 When 0/x Supplying power was stopped by the thermal
shutdown. is displayed:
The supply of power was stopped because a thermal anomaly was
detected in the PoE controller.
Check the power-receiving device or connection cables.
 When 0/x Supplying power was stopped by the PD
disorder (xxxx) is displayed:
Check the information displayed for xxxx.
 MPS Absent:
An error might have occurred on the power-receiving device or a
connection cable.
 Startup Failure:
An error might have occurred on the power-receiving device.
 Short:
The current flowing between the Switch and the power-receiving
device might have exceeded the defined value.
 Classification Failure: [AX2200S]
The class identification between the Switch and the
power-receiving device has failed.
Check the power-receiving device or connection cables.
3.4.6 Communication failures when link aggregation is used
If communication is not possible or if degraded operation is in effect when link aggregation
is used, isolate the cause of the problem according to the failure analysis method in the
following table.
