Ubiquiti UniFi Switch Lite 16 PoE (USW-Lite-16-PoE)

The Ubiquiti UniFi Switch Lite 16 PoE (USW-Lite-16-PoE) is a compact, fanless Layer 2 switch designed for small to medium-sized networks requiring both standard Ethernet and Power over Ethernet (PoE) connectivity. It offers a balance between performance, energy efficiency, and affordability, making it suitable for powering UniFi access points, IP cameras, and other PoE-enabled devices.

 PoE Considerations

While each PoE+ port can deliver up to 30W, the total PoE budget is limited to 45W. This means that simultaneous usage of all PoE ports at maximum capacity is not feasible. For example, powering multiple devices that each require 15W would quickly approach the total budget, potentially necessitating the use of additional power sources or switches for larger deployments.

 Ideal Use Cases

• Small to medium-sized networks requiring a mix of PoE and non-PoE devices

• Environments where silent operation is essential (fanless design)

• Deployments needing basic Layer 2 switching features

• Cost-effective solutions for powering UniFi access points and IP cameras
