PoE > PoE Port Settings (DGS-1100-08P only)
DGS-1100-08P supports Power over Ethernet (PoE) as defined by the IEEE specification. It supplies power
to PD device up to 15.4W for all ports, meeting IEEE802.3af standards.
DGS-1100-08P works with all D-Link 802.3af devices. The Switch also works in PoE mode with all non-
802.3af capable D-Link AP, IP Cam and IP phone equipment via the PoE splitter DWL-P50.
DGS-1100-08P reserves 7 Watts for guard band in order to ensure the connection of the lowest priority PD.
The maximum power used by power devices is defined by the following classification
Class Usage Output power limit by PSE
0 Default 15.4W
1 Optional 4.0W
2 Optional 7.0W
3 Optional 15.4W
The PoE port table will display the PoE status including, Port State, Priority, Power Limit, Power (W), Voltage
(V), Current (mA), Classification, Status. You can select From Port / To Port to control the PoE functions of a
port. DGS-1100-08P will auto disable the ports if port current is over 375mA in 802.3af mode.
NOTE: The PoE Status information of Power current,
Power Voltage, and Current is the power usage
information of the connected PD; please "Refresh" to
renew the information.
Figure 70 – PoE > PoE Port Setting
From Port/To Port: Specifies the PoE function of a port or ports.
State: Select “Enabled” or “Disabled” to configure PoE function for designated port(s). Default is Enabled.
Priority: Configure the power supply priority as “Low”, “Normal”, or “High” on designated port(s). Default is
Normal.
Power Limit: This function allows you to manually set the port power current limitation to be given to the PD.
To protect the DGS-1100-08P and the connected devices, the power limit function will disable the PoE
function of the port when the power is overloaded. Select from "Class 1", "Class 2", "Class 3" and "Auto"
for the power limit. "Auto" will negotiate and follow the classification from the PD power current based on
the 802.3at standard.
User Define: Check the box and input the power budget (from 1.0 to 15.4W) to manually assign an upper
limit of port power budget on designated port(s).
