What is the maximum power per port for power supplying devices?

• A. 5.4 W
• B. 10.4 W
• C. 15.4 W
• D. 20.4 W

Answer: (C)

The maximum power per port for power supplying devices is defined as 15.4 Watts. This value is significant because it adheres to the specifications of Power over Ethernet (PoE) as established in IEEE 802.3af. The 802.3af standard allows devices, such as wireless access points, IP cameras, and VoIP phones, to receive power through an Ethernet cable without needing a separate power supply. This 15.4 Watts per port is sufficient for powering most devices that typically operate in a networked environment. It ensures that these devices can function effectively, providing reliable connectivity and operation. Understanding this power requirement is crucial for network design and deployment, especially when determining the number of devices that can be supported by a given PoE switch or injector.
