PoE Ports
(DGS-1250-28XMP and DGS-
1250-52XMP Only)
Supports the following:
• IEEE 802.3af PoE and IEEE 802.3at PoE+ compliance
• Power (DGS-1250-28XMP: Ports 1 to 24 and DGS-1250-52XMP: Ports
1 to 48) to PD devices up to 15.4 Watt per port (802.3af) or 30 Watt per
port (802.3at) and more sufficiently is able to provide power to PD
devices
• The auto-discovery feature automatically recognizes the connection of
the PD device and immediately provides power
• Automatically disable ports if the port current is over 600mA while.
Other ports will remain active
• Active circuit protection automatically disables the port if there is a
short while other ports remain active
• For 802.3af/at capable devices it will provide the power for the
following classifications below:
Class Usage Max Power used by PD
0 Default 0.44 Watt to 12.95 Watt
1 Optional 0.44 Watt to 3.84 Watt
2 Optional 3.84 Watt to 6.49 Watt
3 Optional 6.49 Watt to 12.95 Watt
4 Optional (802.3at Only) 12.95 Watt to 25.5 Watt
• For 802.3af/at capable devices it will provide the power for the
following classifications below:
• The PoE switch works with all D-Link 802.3af and 802.3at capable
devices and with all non-802.3af and non-802.3at capable D-Link
Access Points, IP Cameras and IP Phones
• The total PoE power budget of the:
o DGS-1250-28XMP is 370 Watts
o
DGS-1250-52XMP is 370 Watts
