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 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 supports PoE 60W on
all copper ports.
NOTE: This section applies to the N1108P-ON/N1124P-ON/N1148P-
ON/N1524P/N1548P/N2024P/N2048P/N2128PX-ON/N2224PX-ON/N2248PX-
ON/N3024P/N3048P/N3132PX-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.
The static power management feature allows operators to reserve a
guaranteed amount of power for a PoE port. This is useful for powering up
devices which draw variable amounts of power and provide them an assured
power range within which to operate. Class based power management
allocates power at class limits as opposed to user defined limits.
