PoE > PoE Port Settings (DGS-1210-28P only)
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.

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 "

" for the power limit. "
Auto
" will negotiate and follow the classification from the PD power current
based on the 802.3at standard.
