Switch Feature Overview 73
PoE 60W Support
The Dell EMC Networking N3024P/N3048P/N3024EP-ON/N3048EP-ON
switches implement 4-pair PoE 60W on the first 12 1G ports. The N3132PX-
ON switches implement PoE 60W on the copper 1G and 5G ports. The
N2128PX-ON switches implement PoE 60W on the 2.5G ports. The N1108P-
ON, N1124P-ON, 1148P-ON, N1524P, N1548P, N2024P, and N2048P switches
do not support PoE 60W.
PoE 60W allows power to be supplied to Class 5 powered devices that require
power up to 60 watts. PoE 60W power must be configured manually. Class-
based and dynamic power allocation is not supported for PoE 60W.
Class D or better cabling is required for feeds in excess of 34.2 watts.
Normally, CAT 5E cabling does meet this requirement.
PoE-capable switches that are connected to another PSE supplying power will
stop supplying power on the affected ports. PSE capability should be disabled
when connecting Dell EMC PoE enabled ports to other PSE equipment.
Powered Device Detection
The switch is capable, based upon configuration, of detecting legacy, AF, or
AT devices in two-pair or four-pair modes. AT detection is initiated first,
followed by AF detection, and if configured, legacy detection. The switch
always supplies full power to the port during power up and prior to
performing detection.
PoE Power Management Modes
PoE-capable switches can be configured to manage powered devices (PD)
using a dynamic, static, or class-based management. The power management
mode is configured using the power inline management command.
Static Power Management
In this mode, the power reserved for the port is the configured limit regardless
of whether the port is powered or not. The device may draw up to the
configured limit. This mode is useful for devices that do not support
LLDP-MED.
Available Power = Power Limit of the Sources – Total Configured Power
