Product Overview

The SL821P-V2 8 Ports PoE Switch is a versatile networking solution designed for businesses needing both power and high-speed data transfer. This 8 ports PoE switch features 8 10/100Base-TX Ethernet ports2 10/100/1000Base-T Ethernet ports, and a 1000Base-X SFP slot for fiber connectivity. Equipped with comprehensive PoE capabilities, ports 2-8 support IEEE 802.3af/at with up to 25.4W per port, while port 1 supports IEEE 802.3BT (PoE++) delivering up to 60W. With intelligent PoE detection, the SL821P-V2 ensures power is supplied only to PoE-compatible devices, preventing damage to non-PoE equipment.

Key Features

  • 8 10/100Base-TX PoE ports2 10/100/1000Base-T uplink ports, and 1 1000Base-X SFP uplink slot for diverse connectivity options.
  • 7 RJ45 ports support IEEE802.3 af/at Ethernet power supply standards with a maximum output power of 25.4W per port.
  • 1 RJ45 port supports IEEE802.3 af/at/poe++/bt Ethernet power supply standards with a maximum output power of 60W per port.
  • Supports one-key switching to VLAN mode and 250m long-distance transmission mode for extended network reach.
  • Digital tube display for real-time monitoring of PoE online utilization rate.
  • All ports support half/full duplex adaptive and automatic MDI/MDI-X functions.
  • All ports support line-speed forwarding for smooth data transmission.
  • Optional network port supports 6KV common mode/4KV differential mode surge protection function.
  • Optional AI network self-healing (watchdog) function for enhanced network reliability.
  • Supports both desktop and wall-mounted installation for flexible deployment.
  • Plug and play design for simple operation and no configuration required.
  • Metal shell and built-in power supply design for excellent heat dissipation and long-term stable operation.
