The switch has PoE functionality
A PoE switch transmits electrical power along with data over twisted-pair Ethernet cabling to powered devices, using standard RJ45 connectors. PoE technology combines power and data transmission, allowing devices like IP cameras and wireless access points to receive power without. The Layer 2 switch is the type of network or Ethernet switch that is most frequently used. Any Layer-2 Ethernet switch that adheres to the OSI model employs MAC addresses to route traffic.

Using PoE switches and non-PoE switches together
Yes, PoE does not interfere with normal switch operation. In addition, many PoE switches can automatically disable the PoE part of the signal for ports that do not need/request/support it, making them more power-efficient. PoE (Power over Ethernet) technology allows switches to deliver both power and data over a single Ethernet cable—perfect for powering devices like IP cameras, VoIP phones, and wireless access points. PoE devices are network equipment that can send out or receive the PoE power along with data, such as PoE switches, IP cameras, wireless access points, while non-PoE devices can only. Good news: PoE and non-PoE switches can absolutely work together —as long as you design the network with power budgeting, standards compliance, and uplink planning in mind. This guide breaks down the differences, the best ways to combine them, and common pitfalls to avoid. But in an organizational setup, we always have devices that are not PoE enabled. Two buildings are for the church (church and kitchen/storage area), the 3rd building is preschool. Each building is connected via older Brocade FWS 648 switches with 10GB SFP Fiber.
