But even though 802.3at power sourcing equipment (PSE) can transmit 15.4W of power, powered devices (PDs) can only reliably receive 12.95W of power due to power dissipation. In 2009, the IEEE introduced the 802.3at standard (also known as PoE+). Two- and four-pair Ethernet The original IEEE 802.3af-2003 PoE standard provides up to 15.4 W of DC power (minimum 44 V DC and 350 mA) on each port.
