gs (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.
Figure 5.87 – 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
