PoE (DGS-3120-24PC and DGS-3120-48PC Only)
The DGS-3120-24PC and DGS-3120-48PC 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 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.
