16/24-Port PoE Switch
@------------------J
Note:
The power supplying mode is depending on the PD specifications. The selected mode
shall supports PSE and PD at the same time. If the PSE and the PD power supplying mode
are not the same (such as the PSE does not support the spare wire power supplying, or the
PD supports spare wire supplying only), please use converter to provide power to the PD.
4. PD
PD refers to the device receiving power from the PSE. It includes IP phone, wireless AP,
portable recharger, POS, network camera and etc.
When the PD enjoys the power from the PoE device, it can connect to other device to
backup the power. Refer to Table 7-1 for port detailed setup information.

Port
In the panel figure to select the PoE port. The select port(s) will be displayed in the
Selected Ports list at the bottom of the interface.
Note
Port 1 and 2 support Hi-PoE.
Power Status Enable or disable PoE on the selected ports.
• The system does not supply power to or reserve power for the PD connected to a
PoE port if the PoE port is not enabled with the PoE function.
• You are allowed to enable PoE for a PoE port if the PoE port will not result in PoE
power overload; otherwise, you are not allowed to enable PoE for the PoE port.
By default, PoE is disabled on a PoE port.
Note
PSE power overload-When the total amount of the power consumption of all ports
exceeds the maximum power of PSE, the system considers the PSE is overloaded.
Total power
It is to set PoE port total power consumption reserved value.
consumption
The PoE total power consumption value refers to the total power consumption for the
reserved value PD from the all PoE port. When the connected PD power consumption is higher than
the PoE total power consumption, it stops providing power to the PD.

Refer to Figure 7-2 for setup interface.

7.2 PoE Event Statistics
Figure 7-3
In Figure 7-3, it is to display the PoE event statistics of each port. It includes Overload, Short
Circuit Limit, DC Disconnect, Server Short Circuit, and Thermal Shutdown.
Refer to Table 7-2 for PoE event parameters.
Name
Note
Overload
The working power current of single port has exceeded the current threshold.
Short Circuit Limit
Short-circuit when powering chip starts sending power to the port.
DC Disconnect
Single port power is off.
Server Short-circuit Short-circuit when the powering chip is sending out power.
Thermal Shutdown The powering chip temperature is too high resulting from short-circuit or other
reason.

7 .3 Green PoE
In Figure 7-4, it is to set PoE energy-saving parameters. The PoE function is off in the specified
period to save power. When the period is over, the port auto resumes providing power.
