Power Over Ethernet
The NetVanta 3148 PoE and NetVanta 4148 PoE units provide PoE. PoE provides the ability to
detect attached powered devices (PDs) and deliver 48 VDC to PD via Ethernet cabling. The
NetVanta 3148/4148 PoE Series is fully compliant with the IEEE 802.3af PoE and IEEE 802.3at
PoE+ standards. By default, the PoE router discovers and provides power to IEEE-compliant
PDs. The NetVanta 3148/4148 Series also supports legacy PDs.
The NetVanta 3148/4148 PoE Series has a PoE budget of 200 W. Caution should be taken not to
add greater than 200 W of load from powered devices. A 200 W PoE budget enables the user to
power: 8 ports at 15.4 W each, 6 ports at 25.5 W each, or any combination as long as the sum of
load is less than 200 W. The NetVanta 3148/4148 PoE Series can also provide a reduced PoE
budget of 7 W to all 8 ports (for a total of 56 W PoE).
