DGS-1210-28P supports Power over Ethernet (PoE) as defined by the IEEE specification. It supplies power
to PD device up to 15.4W for all ports or 30W for port 1~4, meeting IEEE802.3af standards and pre-802.3at
standards.
DGS-1210-28P works with all D-Link 802.3af or 802.3at capable 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.
IEEE 802.3at defined that the PSE provides power according to 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
4
Reserved 30W
The PoE port table will display the PoE status including, Port Enable, Power Limit, Power (W), Voltage (V),
Current (mA), Classification, Port Status. You can select From Port / To Port to control the PoE functions of
a port. DGS-1210-28P will auto disable the ports if port current is over 375mA in 802.3af mode or 625mA in
pre-802.3at 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 4.115 – 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.
Time Range: Select the PoE time profile configured from Time-Based PoE > Time Range Settings to enable
the time-based PoE function on designated port(s). Default setting is N/A.
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-1210-28P 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",
“Class 4”
and "Auto" for the power limit. "Auto" will negotiate and follow the classification from the PD power current
based on the 802.3at standard.
