Product Overview
The SL821P-E PoE 8 Port Switch is an advanced networking solution designed for establishing and powering devices efficiently. It features 8 10/100Base-TX Ethernet ports, 2 10/100/1000Base-T Ethernet ports, and 1 1000Base-X SFP slot, making it an ideal choice for reliable connectivity in various environments. All ports (1-8) support the IEEE802.3 af/at PoE (Power over Ethernet) protocol, providing a maximum output power of 25.4W per port. This switch automatically detects whether connected devices support PoE, ensuring that power is only supplied to compatible devices, thus preventing potential damage to non-PoE devices.
Key Features
- 8 10/100Base-TX PoE ports, 2 10/100/1000Base-T uplink ports, and 1 1000Base-X SFP uplink slot for comprehensive networking capabilities.
- Each PoE port adheres to the IEEE802.3 af/at PoE protocol, delivering a maximum output of 25.4W per port.
- Equipped with a DIP switch that enables the reduction of transmission rates to 10Mbps for ports 1-8, allowing for an extended maximum distance of 250m using existing twisted pairs.
- Ports 1-8 are isolated from each other for mutual network isolation, while still enabling communication with uplink ports (9-10), minimizing collision and broadcast domains to enhance network efficiency.
- Supports 10/100Mbps auto-negotiation for ports 1-8 and 10/100/1000Mbps auto-negotiation for ports 9-10 for optimal compatibility.
- Supports half/full duplex adaptive mode and automatic MDI/MDI-X functionality for seamless setup and operation.
- All Ethernet ports support wire-speed forwarding, ensuring smooth and efficient data transmission.
- Versatile installation options with support for both desktop and wall-mounted setups.
- Plug-and-Play operation makes installation and configuration a breeze with no special setup required.
- Constructed with a durable metal casing and an internal power supply for excellent heat dissipation, ensuring long-term stability and performance.
- Optional features include 6KV common mode/4KV differential mode surge protection and AI network self-healing (watchdog) functionality for enhanced resilience.
Ideal Applications
The SL821P-E PoE 8 Port Switch is perfectly suited for video surveillance networking, making it ideal for deployment in hotels, shops, supermarkets, residential homes, and small to medium-sized enterprises.
