PoE

The DGS-3420-28PC and DGS-3420-52P switches support Power over Ethernet (PoE) as defined by the IEEE 802.3af
and 802.3at. All ports can support PoE up to 30W. All the ports can supply about 48 VDC power to Powered Devices
(PDs) over Category 5 or Category 3 UTP Ethernet cables. The Switch follows the standard PSE (Power Sourcing
Equipment) pinout Alternative A, whereby power is sent out over pins 1, 2, 3 and 6. The Switches work with all D-Link
802.3af capable devices.
The Switch includes the following PoE features:
•
Auto-discovery recognizes the connection of a PD (Powered Device) and automatically sends power to it.
