Product Overview
The SG2421P-V2 24 Port PoE Network Switch is a high-performance solution for demanding network environments. This poe network switch 24 port features 26 10/100/1000Base-T Ethernet ports, and 1 1000Base-X SFP slot for flexible fiber uplinks. 24 of the Ethernet ports are IEEE802.3 af/at compliant, delivering up to 25.4W of PoE power per port. One port supports the IEEE 802.3BT (PoE++) standard, providing up to 60W for high-power devices. As a PoE power supply device, this switch can automatically detect whether the powered device supports PoE power supply. It only supplies power to compliant powered devices, effectively preventing damage to non-PoE powered devices. Enhanced with features like extended transmission distance and port isolation, this switch ensures optimal performance and security.
Key Features
- 24 10/100/1000Base-T PoE ports, 2 10/100/1000Base-T uplink port, and 1 1000Base-X SFP uplink slot offer versatile connectivity.
- Ethernet ports support IEEE802.3 BT/af/at protocols for flexible power delivery.
- Supports one-key switching to VLAN mode and 250m long-distance transmission mode. (Ports 1-24 operate at 10Mbps in extended mode.)
- Supports digital tube for real-time display of PoE online utilization rate.
- All Ethernet ports support half/full duplex adaptive and automatic MDI/MDI-X functions.
- All Ethernet ports support line-speed forwarding for optimal performance.
- Ports 1-24 can be isolated from each other to isolate collision and broadcast domains.
- Supports desktop and wall-mounted installation.
- Plug and play for easy setup, no configuration required.
- Durable metal shell and built-in power supply design for excellent heat dissipation and long-term stability.
- Optional: 6KV common mode/4KV differential mode surge protection.
- Optional: AI network self-healing (watchdog) function.
