    48 Port Unmanaged Fast Ethernet Switch, 10/100Mbps, Rackmount, 19" Steel Case

    What This Product Does

    The ES1-2865/48P 10/100Mbps Switch is designed to meet the needs of the most demanding workgroup and departmental connectivity requirements. All 48 ports support auto MDI/MDIX, no need to worry about the cable type, simply plug and play. Moreover, with the innovative energy-eff cient technology, ES1-2865/48P can save up to 50%* of the power consumption and 80% of the packaging material can be recycled, making it an eco-friendly solution for your business network.

    Primus Cable Green Technology

    This new generation ES1-2865/48P 10/100Mbps Switch features the latest innovative energy-effcient technologies that can greatly expand your network capacity with much less power. It automatically adjusts power consumption according to the link status and cable length to limit the carbon footprint of your network. It also complies with the EU’S RoHS, prohibiting the use of certain hazardous materials. Besides, 80% of the packaging material can be recycled.

    High Performance

    Featuring non-blocking switching architecture,TL-SF1048 forwards and filters packets at full wire-speed for maximum throughput. And IEEE 802.3x flow control for Full Duplex mode and backpressure for Half Duplex mode alleviate the traffic congestion and make TL-SF1048 work reliably.

    Easy to Use

    The auto features of this Fast Ethernet switch make installation plug and play and hassle-free. No configuring is required. Auto MDI/MDIX eliminates the need for crossover cables. Auto-negotiation on each port senses the link speed of a network device (10, 100Mbps) and intelligently adjusts for compatibility and optimal performance.


    • Innovative energy-efficient technology saves power up to 50%.
    • 100% Data filtering rate eliminates all error packets.

    Additional Information

    Ethernet Switch Accessories

    An Ethernet network switch is a telecommunication device that receives data transmitted from a connected device and relays it to a specific device. Ethernet switches create separate collision domains per switch port, allowing for simultaneous data transfers to occur without interference. They also reduce the number of broadcast domains, and don’t require heavy CPU usage. The Ethernet switch manages the flow of network traffic more efficiently and in a safer manner than repeater hubs. It allows for the flow of data between connected devices. Ethernet switches come in both managed and unmanaged varieties. Unmanaged switches are the easy to install, plug and play variety.
