PoE Specification
1. Supplies power to PD device up to 15.4W per port, meeting
IEEE802.3af standards and more sufficiently is able to provide
power to PD devices
2.
uto discovery feature, automatically recognize the connection of PD
device and immediately sends power to it
3. Auto disable port if the port current is over 350mA while other ports
remain active
4. Active circuit protection, automatically disables the port if there is a
short while other ports remain active
5. PD should be able to receive the power following the classification
below
Class Usage Max power used by PD
0 Default 0.44 to 12.95W
1 Optional 0.44 to 3.84W
2 Optional 3.84 to 6.49W
3 Optional 6.49 to 12.95W
4 Not allowed Reserved
6. PSE should be provide the power following the classification below
Class Usage Max power used by PD
0 Default 15.4W
1 Optional 4.0W
2 Optional 7.0W
3 Optional 15.4W
4 Reserved 15.4W
7. DES-3028P/DES-3052P should follow the standard PSE pin-out
standard of Alternative A which is sending out power over number
1,2,3,6 pins of 8 wires of CAT5 UTP cable
8. DES-3028P/DES-3052P works with all D-Link 802.3af capable
devices
9. DES-3028P/DES-3052P works with all non-802.3af capable D-Link
AP, IP Cam and IP phone via DWL-P50
