The DES‎-1024D 24‎-Port Fast Ethernet Unmanaged Desktop Switch is designed to enhance workgroup performance while providing a high level of flexibility‎.‎ Powerful yet easy to use‎,‎ this device allows users to simply plug any port to either a 10Mbps or 100Mbps network to multiply bandwidths‎,‎ boost response time and satisfy heavy load demands‎.‎

Ideal for Basic Networking Tasks

With the D‎-Link DES‎-1024D‎,‎ you can easily expand your network by adding more computers or devices with speeds up to 200 Mbps per port in full‎-duplex mode‎.‎

Auto‎-Sensing 10/100 Ports

The DES‎-1024D use auto‎-sensing 10/100 Mbps ports‎,‎ allowing a small workgroup to flexibly connect to 10 or 100 Mbps devices to create an integrated network‎.‎ Each port automatically adjusts for straight‎-through or crossover cables to make the right link‎.‎

Flow Control for Secure Transmission

802.3x flow control on each port minimizes dropped packets when the port’s receiving buffer is full‎.‎

Quality of Service ‎(‎QoS‎)‎

The switches provide 802.1p priority queues for QoS‎,‎ allowing users to run bandwidth‎-sensitive applications such as multimedia and VoIP Internet telephone without data flow bottlenecks that can degrade the quality of the network connection‎.‎

Save on Energy Costs

The switches support IEEE802.3az EEE which enables the switches to reduce power consumption when the switches are at low utilization‎,‎ allowing users to save on power usage and costs‎.‎ During these periods of low utilization‎,‎ the switches can enter a low‎-power state and use up less power than regular operations‎.‎
