Moxa Managed Ethernet Switch (UI_2.0_FW_5.x) User Manual
PoE Diagnostic
PoE Diagnostic helps users determine the PD conditions. The system provides the user with conf iguration
options; select the best option for your PDs. It will automatically detect and suggest the conf igurations
when users click on this page and the status will be refreshed when you click the ref resh button.
Diagnose Configuration
Device Type
No connection to the port
A NIC is connected to the port
An IEEE 802.3af PD is connected to the port
An IEEE 802.3at PD is connected to the port
Legacy PoE Device
A legacy PD is connected to the port, and the PD’s detected voltage is too high or
low, or the PD’s detected capacitance is too high.
Unknown PD connected to the port
2-Pair PD A 802.af , 802.3 at, or legacy 2-pair PD
A 4-Pair PD that uses all 8 pins of the RJ-45 connector to receive PoE output
Classification
N/A The port is not classif ied
Unknown class f or the port; in this case it will usually be higher than class 4
Voltage (V)
No voltage output on the port
Display the voltage of the port
PoE Port Configuration Suggestion
Disable PoE power output
When detecting a NIC or unknown PD, the system suggests disabling PoE
power output.
Enable “Legacy PD Detection”
When detecting a higher capacitance of PD, the system suggests enabling
Legacy PD Detection.
Select Force Mode
When detecting higher/lower resistance or higher capacitance, the system
suggests selecting Force Mode.
Select IEEE 802.3af /at auto
mode
When detecting an IEEE 802.3 af /at PD, the system suggests selecting 802.3
af/at Auto mode.
Select high power output
When detecting an unknown classification, the system suggests selecting
