Power Over Ethernet Commands Dell EMC Networking PoE N1100P-ON, N1108EP-ON, N1524P, N1548P, N2024P, N2048P, N2124PX-ON, N2148PX-ON, N300EP-ON, N3132PX-ON switches implement the PoE, PoE+, or PoE 60W for power sourcing equipment (PSE), depending on the switch model. IEEE 802.3at allows power to be supplied to Class 4 powered devices (PD) that require power up to 30 Watts or PoE 60W (UPoE) to Class 4 devices on certain ports. This allows deployment of powered devices that require more power than the IEEE 802.3af specification allows. PoE+ 802.3at is compatible with 802.3af. The Dell EMC Networking N2224PX-ON, and N2248PX-ON switches implement an IEEE 802.3bt Type 3 PSE. This capability supports 60W power delivery in a standards-compliant implementation as well as power negotiation using LLDP. The Dell EMC Networking N3024EP/N3048EP/N3208PX-ON/N3224PON/N3224PX-ON/N3248P-ON/N3248PXE-ON switches support delivery of up to 60W of power on the first 12 interfaces of each stack unit. The Dell EMC Networking N2128PX-ON supports PoE 60W on the four 2.5G interfaces. The Dell EMC Networking N3132PX-ON and N3200PX-ON switches support PoE 60W on all copper ports. NOTE: This section applies to the N1108EP-ON/N1108P-ON/N1124P-ON/N1148PON/N1524P/N1548P/N2024P/N2048P/N2128PX-ON/N2224PX-ON/N2248PXON/N3024P/N3048P/N3132PX-ON/N3208PX-ON/N3224P-ON/N3248P-ON/N3248PXEON/N3224PX-ON/ switches. Flexible Power Management The Dell EMC Networking PoE solution provides power management which supports power reservation, power prioritization and power limiting. The operator can assign a priority to each PoE port. When the power budget of the PoE switch has been exhausted, the higher priority ports are given preference over the lower priority ports. Lower priority ports are forcibly stopped to supply power in order to provide power to higher priority ports. Switch Management Commands 2146
