HPE Aruba 1-Port 15.4 W PoE Injector. 802.3af PoE 15.3 Watt. Maximum PoE power per port: 15.4 W. RJ-45 speed: 10/100/1000 Mbit/s. The HPE Aruba AP-POE-AFGE PoE Injector features a Gigabit Ethernet port that can deliver up to 15.4 watts of power. 802.3af PoE. The IEEE 802.3af standard provides a maximum of 15.4 watts of power on each PoE port with a voltage of up to 48 volts. The standard assumes that after line losses, 12.95 watts of usable power remain or can be drawn to avoid exceeding the maximum power output. Power over Ethernet (PoE). With Power over Ethernet, you can power compatible devices through the network cable. This significantly reduces cabling efforts for end devices such as wireless access points, IP phones, and IP cameras, while also allowing for high flexibility in the placement of these devices.
