Power Over Ethernet

Feature Description
802.3af PoE or 802.3at PoE+ Delivered over Any of the RJ-45 Ports Within the Listed Power Budgets Switches support 802.3af, 802.3at, and Cisco pre-standard (legacy) PoE on port 1 to port 4 with maximum power of 30 W per port; switches support 802.3af and Cisco pre-standard (legacy) PoE on other RJ-45 ports with maximum power of 15.4 W per port.
This applies to all PoE-enabled models; the maximum number of ports providing PoE power simultaneously is determined by the total PoE budget for the switch, and the actual power requirement of PD devices.
The total power available for PoE per switch is as follows:
Model Name Power Dedicated to PoE Number of Ports That Support PoE
SF220-24P 180 W 24
SF220-48P 375 W 48

180 W 24
