2.2.2 Power Input
The PE-3004 is also equipped with one 4-pin power plug (12V,
6A max) for additional power supply. For most cases, the power
obtained from PCIe bus is sufficient for the PoE devices, and you do
not need to supply extra power to the card.
In case the external power is needed, you can use 4-pin ATX power
connector (+5V/Red, GND/Black, GND/Black, +12V/Yellow) inside
the host computer. Please always confirm the polarity before you
plug into the onboard 4-pin power plug.
