Power Over Ethernet (PoE) Plus Configuration
The Dell Networking N2024P/N2048P and N3024P/N3048P switches support
PoE Plus configuration for power threshold, power priority, SNMP traps, and
PoE legacy device support. PoE can be administratively enabled or disabled
on a per-port basis. Power can also be limited on a per-port basis.
PoE Plus Support
The Dell Networking N2024P/N2048P and N3024P/N3048P switches
implement the PoE Plus specification (IEEE 802.1at), in addition to the
IEEE 802.3AF specification). This allows power to be supplied to Class 4 PD
devices that require power greater than 15.4 Watts. Each port is capable of
delivering up to 34.2W of power. Real-time power supply status is also
available on the switch as part of the PoE Plus implementation.
NOTE:
The Dell Networking N2024P/N2048P and N3024P/N3048P switches
support PoE Plus. The PoE Plus features do not apply to the other models in the
Dell Networking N2000/N3000/N4000 series.
