Description
Choose what the PoE Injector Hub should do following power-up: transmit a DHCP request, or manual setting (Disable).
The DHCP client function only works if you haven't assigned a static IP address that different than the PoE Injector Hub default IP. Once the default IP has been changed the DHCP will not effective and the PoE Injector Hub will continue using the manually entered static IP. If you have changed thePoE Injector Hub to a static IP address, you can set the IP address back to its default IP address or you can reset the PoE Injector Hub back to factory default. And then you can enable the DHCP client function to work.
The factory default is Disable.
The IP address of the PoE Injector Hub.. The factory default value is 192.168.0.100.
The IP subnet mask of the PoE Injector Hub.. The factory default value is 255.255.255.0.
The default gateway of the PoE Injector Hub.. The factory default value is 192.168.0.254.
This field helps to identify the description of PoE Injector Hub.

4.4 PoE
Power Management:
In a power over Ethernet system, operating power is applied from a power source (PSU-power supply unit) over the LAN infrastructure to powered devices (PDs), which are connected to ports. Under some conditions, the total output power required by PDs can exceed the maximum available power provided by the PSU. The system may a prior be planed with a
PSU capable of supplying less power than the total potential power consumption of all the PoE ports in the system. In order to maintain the majority of ports active, power management is implemented.
The PSU input power consumption is monitored by measuring voltage and current .The input power consumption is equal to the system’s aggregated power consumption .The power management concept allows all ports to be active and activates additional ports, as long as the aggregated power of the system is lower than the power level at which additional PDs cannot be connected .When this value is exceeded, ports will be deactivated, according to user-defined priorities. The power budget is managed according to the following user-definable parameters: maximum available power, ports priority, maximum allowable power per port.
This section provides PoE (Power over Ethernet) Configuration and PoE output status of PoE Injector Hub, screen in Figure

Total Limit. Set limit value of the total POE port provided power to the PDs.
For POE-1200, the total PoE power reservation from Port-1~12 is up to 110W
For POE-2400, the total PoE power reservation from Port-1~24 is up to 220W

Set port priority for the POE power management
It can choose the “port priority”, value is “1~4”. High priority is “1”.
Class 0 is the default for PDs. However, to improve power management at the PSE, the
PD may opt to provide a signature for Class 1 to 3.
The PD is classified based on power. The classification of the PD is the maximum power that the PD will draw across all input voltages and operational modes. A PD shall return
Class 0 to 3 in accordance with the maximum power draw as specified by Table 4.1.
It shows the PoE device current Amp.
It shows the PoE device current watt.
It can limit the port PoE supply watts.
Per port maximum value must less 15.4, total ports values must less than the Power
Reservation value.
Once power overload detected, the port will auto shut down and keep on detection mode until PD’s power consumption lower than the power limit value.
PD Classifications
A PD may be classified by the PSE based on the classification information provided by the PD. The intent of PD classification is to provide information about the maximum power required by the PD during operation. Class 0 is the default for PDs. However, to improve power management at the PSE, the PD may opt to provide a signature for Class 1 to 3.
The PD is classified based on power. The classification of the PD is the maximum power that the PD will draw across all input voltages and operational modes.
A PD shall return Class 0 to 3 in accordance with the maximum power draw as specified by Table 4-1.
