Port Description

8 × 10/100/1000BASE-T PoE ports (port 1: PoE++ up to 60W; ports 2-8: PoE+ up to 25.4W each) + 2 × 10/100/1000BASE-T uplink ports (ports 9-10). Total PoE budget: 120W.
  • 8 gigabit PoE ports with auto-sensing: 1 port supports up to 60W (PoE++), 7 ports support up to 25.4W (PoE+/PoE)
  • DIP switch enables VLAN isolation or 250m long-distance transmission on ports 1-8
  • Digital tube dynamically shows total PoE power usage – quick health check without logging in
  • Plug-and-play, no setup required; auto MDI/MDI-X and auto-negotiation on every port
  • Metal housing with internal power supply; supports desktop or wall-mount installation









Why choose this 8 port PoE switch unmanaged for your network deployment?

If you’re setting up IP cameras, VoIP phones, or wireless access points in a small office, retail store, or home environment, you need a switch that delivers power and data over a single cable without extra configuration. This 8 port PoE switch unmanaged does exactly that – it automatically detects PoE devices (IEEE 802.3 af/at/bt) and supplies power only to those that need it, protecting your non-PoE gear from damage.

Key strengths you’ll notice on the job

The first port supports PoE++ up to 60W – enough to power high-demand devices like PTZ cameras or outdoor bridges. The remaining seven PoE ports deliver 25.4W each, covering most standard endpoints. With a total PoE budget of 120W, you can run several cameras or APs without needing extra power injectors. The switch also features a DIP switch that toggles between standard 100m mode and 250m extend mode: in extend mode, ports 1-8 are isolated from each other but can still communicate with the two uplink ports, cutting down broadcast storms and extending reach for long cable runs.

Where it fits best

This 8 port PoE switch unmanaged is a practical choice for video surveillance in hotels, supermarkets, and small-to-medium businesses. It’s also good for extending your network to a workshop or garage where running separate power lines is inconvenient. The metal casing and internal power supply make it durable for 24/7 operation, and the natural heat dissipation keeps it running cool without a fan noise.
