Description

• Physical Port:
  • 24-port 10/100/1000BASE-T RJ45 copper with PoE injector function
  • 4 10/100/1000BASE-T RJ45 copper interfaces
  • 2 1000BASE-X SFP combo interfaces, shared with Ports 27~28
• Power over Ethernet:
  • Complies with IEEE 802.3at Power over Ethernet Plus end-span PSE
  • Up to 24 ports of IEEE 802.3af / 802.3at devices powered (ports 1~24)
  • Supports PoE power up to 32 watts for each PoE port, with a total PoE budget of 250W.
  • Each port supports 54V DC power to PoE powered device.
  • Auto detects powered device (PD)
  • Supports PD alive function.
  • Circuit protection prevents power interference between ports.
  • Remote power feeding up to 100m in standard mode with 250m in extend mode
• Switching:
  • Hardware-based 10/100/1000Mbps auto-negotiation and auto MDI/MDI-X
  • Supports IEEE802.3x flow control in full-duplex mode and backpressure in half-duplex mode
  • Integrates address look-up engine, supporting 8K absolute MAC addresses
  • 9K jumbo frame supports all speeds (10/100/1000Mbps)
  • Hardware-based DIP switch for Standard, VLAN or Extend mode selection;
    • VLAN mode: Ports 1~24 cannot communicate with each other, but can communicate with the uplink ports 25~28 and SFP ports 27~ 28
    • Extend mode: Ports 1~8 have data rate of 10Mbps. The farthest transmission distance is up to 250 meters and all ports can communicate with each other.
  • VLAN mode is to isolate ports to prevent broadcast storm and defend DHCP spoofing
  • Automatic address learning and address aging
• Hardware:
  • 19-inch rack-mount size, 1U height
  • LED indicators for system power, per port PoE ready and PoE activity, speed, Link/Act
  • 2 fans to provide stable and efficient power performance
  • Supports contact discharge of 6KV DC and air distance discharge of 8KV DC for Ethernet ESD protection
  • Supports 6KV surge immunity
