BUZY NetworksBUZY's take on this product:

The USW-Flex-2.5G-8-PoE delivers multi-gigabit connectivity in a flexible, compact form factor perfect for edge deployments where space is limited but performance cannot be compromised. This switch bridges the gap between standard gigabit infrastructure and 10G backbones, offering eight 2.5 GbE PoE++ ports that provide the bandwidth needed for modern devices like WiFi 6/6E access points, high-resolution IP cameras, and demanding IoT equipment. The 10 GbE RJ45/SFP+ combination uplink port ensures your edge switch never becomes a bottleneck, supporting both copper and fiber connectivity to your network core.

  • Flexible powering options: Deploy with PoE+++ input (57W PoE budget), PoE++ input (37W budget), PoE+ input (12W budget), or optional AC adapter for full 196W PoE++ output capacity
  • Multi-gigabit performance: 2.5 GbE ports eliminate the bottleneck between gigabit switches and high-performance wireless access points or NVR systems
  • Versatile deployment: Compact design allows installation in tight spaces, equipment closets, or remote locations where running dedicated power isn’t practical
  • Future-proof connectivity: 10G uplink with SFP+ support ensures compatibility with existing fiber infrastructure and room for network growth

Managed through the intuitive UniFi Network Controller, the USW-Flex-2.5G-8-PoE integrates seamlessly with your existing UniFi ecosystem, providing centralized configuration, monitoring, and troubleshooting across all network devices. The switch’s flexible powering capability makes it ideal for expanding networks without electrical work—simply connect via PoE from an upstream switch and immediately add multi-gigabit capacity where needed. Whether you’re building out a modern wireless network with WiFi 6E access points, upgrading surveillance infrastructure with 4K cameras, or extending high-speed connectivity to remote offices, this switch delivers professional-grade performance with the deployment simplicity that defines the UniFi experience.

    Great service! Prices are very competitive and shipping was extremely fast. Would happily recommend to business colleagues family and friends. Will be buying from them again.
    My only very tiny gripe is that don’t offer PayPal or Afterpay payments and they don’t offer pricing on some of the Unifi Enterprise gear on the website

    Great switch. I missed the fact there is no power supply. Makes it not such good value, but then it is a quality switch. Buzy customer service is top class.
