    Durable Metal

Power over Ethernet, Flexible Network Deployment

Compliant with the IEEE 802.3af/at PoE standards, the switch supports a total PoE power budget of 250 W with 30 W max per PoE+ port. When total power consumption exceeds 250 W, the intelligent power management will cut the lower priority ports power to protect devices from damage.

Instantaneous Multi-mode Toggles

  • Up to 250m Transmissions

    With extend mode, the PoE transmission distance reaches up to 250m** —perfect for IP Camera deployment in large areas.

  • One-click Port Priority

    Priority mode guarantees the quality of sensitive applications like video and voice in critical business areas by prioritizing the data of ports.

  • Traffic Separation for Security

    Isolation Mode easily divides traffic for ports to avoid snooping/tampering and isolates broadcast storm for higher security.

  • PoE Auto Recovery

    Recovery mode helps automatically detect and reboot PD devices, such as cameras and APs, when they fall offline or go unresponsive—all without needing manual monitoring and restarts.

*PoE budget calculations are based on laboratory testing. Actual PoE power budget is not guaranteed and will vary as a result of client limitations and environmental factors.

**The speed of the ports in extend mode will downgrade to 10 Mbps. The actual transmission distance may vary due to power consumption of PoE-powered devices or the cable quality and type.

Numbers after different modes represent the effective ports for that mode.
