Which of the following is a requirement for PoE?

• A. A switch that only runs non-PoE devices
• B. Proper cabling that can handle data speeds
• C. A power source that is not from the network
• D. A device that does not use Ethernet cables

Answer: (B)

The requirement for Power over Ethernet (PoE) involves ensuring that the cabling used can handle not only data transmission but also power delivery. In a PoE setup, both electrical power and data are transmitted through the same Ethernet cables, typically using Cat 5e or higher cabling. This means that the cables need to be able to handle the voltage and amperage required for the PoE devices. Proper cabling ensures that devices can receive sufficient power without affecting data integrity, making it a critical component of implementing PoE successfully. Considerations such as using a switch that operates solely with non-PoE devices, arranging a power source independent of the network, or connecting devices that do not utilize Ethernet cables do not fulfill the requirements for PoE. For PoE to function optimally, specific cabling is essential to support simultaneous data and power flow effectively.
