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
0
1
2
3
4
•
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
