Power over Ethernet (PoE) Plus Features
For information about configuring PoE Plus features, see "Managing General
System Settings " on page 389.
Power Over Ethernet (PoE) Plus Configuration
The Dell Networking N1524P/N1548P, 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 N1524P/N1548P, 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.
UPOE Support
The Dell Networking N3024P/N3048P switches implement 4-pair Universal
Power over Ethernet (UPOE) on the first 12 ports. This allows power to be
supplied to Class 5 powered devices that require power up to 60 watts. UPOE
power must be configured manually. The N1424P/N1548P/N2024P/N2048P
switches do not support UPOE. High-power mode must be enabled in
addition to four-par forced mode for the switch to deliver power on all four
pairs. Class D or better cabling is required for feeds in excess of 34.2 watts.
Normally, CAT 5E cabling does meet this requirement.
NOTE: The Dell Networking N1524P/N1548P, N2024P/N2048P, and
N3024P/N3048P switches support PoE Plus and UPOE on selected ports. The PoE
Plus and UPOE features do not apply to the other models in the Dell Networking
N2000/N3000/N4000 Series.
