Description
Power limit mode
Allow to configure power limit mode of Web Smart Device. It can choose :
Port Priority
Deliver PoE power by port priority setting
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
Power reservation
Show the total watts usage of PoE Switch.
PoE Function
Can enable or disable the PoE function.
Priority
Set port priority for the POE power management
It can choose the
“port priority”
, value is
“1~4”
. High priority is
“1”
.
Device class
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
.
Current(mA)
It shows the PoE device current Amp.
Consumption [W]
It shows the PoE device current watt.
Power Limit
It can limit the port PoE supply watts.
Per port maximum value must less
15.4, t
otal 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 classifi-
cation 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.
