cases, you can use the 4-pin power plug (+5V/Red, GND/Black, GND/Black, +12V/Yellow)
from the ATX power supply inside the host computer. Please always confirm the polarity before
you plug the external power into the on-board 4-pin power connector.
3.5 Connect a PoE or Non-PoE Device
PoE, or Power over Ethernet, is a technology to supply electrical power along with data on
a standard Ethernet cable. By detecting and classifying the connected device before
supplying power to device, PCIe-PoE354at and PCI-PoE352at can work with
both PoE
Powered Devices (PD) and regular Ethernet devices.
A CAT5 or CAT6 cable is usually used for PoE applications. Since PCIe-PoE354at and
PCIe-PoE352at are designed for Gigabit Ethernet connectivity, a CAT-6 cable is highly
recommended. Per IEEE 802.3at specification, each port of PCIe-PoE354at/352at can
delivers 25.5 W of power to a PoE PD device over a cable of up to 100 meters.
