Product Overview

Introducing our Switch Gigabit PoE 8 Port, a versatile and efficient networking solution designed to support both power and data transmission for various applications. This switch features 8 10/100Base-TX Ethernet ports, 2 10/100/1000Base-T Ethernet ports, and 1 1000Base-X SFP slot. Ports 1-8 comply with IEEE 802.3 af/at standards for Power over Ethernet (PoE), each providing a maximum output power of 25.4W. The switch automatically detects PoE-compatible devices and supplies power only to them, effectively preventing damage to non-PoE devices.

With a unique feature that allows ports 1-8 to be forced to operate at 10M using a switch, this device can achieve transmission distances of up to 250m over existing twisted-pair cabling. Furthermore, ports 1-8 are isolated from each other while permitting communication with the uplink ports (9-10), which helps to isolate collision and broadcast domains, reducing broadcast storms, and enhancing overall network efficiency. This makes the Switch Gigabit PoE 8 Port an ideal choice for video surveillance networks in hotels, shops, supermarkets, residential homes, and small to medium-sized enterprises.

Key Features

  • 8 PoE Ports: 8 10/100Base-TX PoE ports, 2 10/100/1000Base-T uplink ports, and 1 1000Base-X SFP uplink port for versatile connectivity.
  • Power over Ethernet: Each of the 8 RJ45 ports supports the IEEE 802.3 af/at standard, delivering a maximum output power of 25.4W per port.
  • VLAN Switching: Supports one-click switching to VLAN mode for enhanced network segmentation.
  • Extended Transmission: Capable of ultra-long-distance transmission up to 250m for ports 1-8.
  • Adaptive Speed: Ports 1-8 support 10/100Mbps adaptive speed, while ports 9-10 support 10/100/1000Mbps adaptive speed.
  • Collision Domain Isolation: Ports 1-8 are isolated from each other, enhancing network efficiency by reducing broadcast storms.
  • Line-Speed Forwarding: All ports support line-speed forwarding for smooth and efficient data transmission.
  • Optional Surge Protection: Provides 6KV common mode and 4KV differential mode surge protection for increased reliability.
  • AI Network Self-Healing: Optional AI network self-healing (watchdog) functionality for automatic recovery from network issues.
  • Easy Installation: Plug-and-play design with no configuration required, making it simple to set up and use.
  • Durable Design: Metal casing with a built-in power supply offers excellent heat dissipation for long-term stable operation.
