D-Link DGS-1024D Unmanaged Switches

The first of the Green Ethernet products the DGS-1024D provides 3 key benefits to end users through its cutting edge innovative eco-friendly technology Reduces power consumption & creates less heat Extended product life Reduces Operating CostsPower Savings by Number of Connected Ports and Link StatusComputers do not require Internet access all the time; neither do switches utilize all ports at all times. When a computer or network equipment is shutdown, switches often remain on and continue to consume considerable amount of power. With Green Ethernet technology, D-Link switches can automatically detect link status and reduce power usage of ports that are idle. Computers or any connecting parties set to standby mode (not power off), however, will not provide significant power savings.Power Savings by Cable LengthThe Green Ethernet switches have the ability to analyze the length of any Ethernet cable connected to them for adjustment of power usage accordingly. Shorter lengths require less power.Overall Power Savings Per DayFor a traditional switch, power consumption remains constant even when the ports are not in use. In a standard workday scenario where PCs are used for 10 hours a day and powered off 14 hours a day, and connected to the switch using 20 meter cables, D-Link's Green Ethernet can save up to 25% power used for each system.Get the blazing speed of Gigabit Ethernet with the D-Link GigaExpress DGS-1024D, an 24-port 10/100/1000Mbps Gigabit Switch that delivers power, performance, and reliability in one cost-effective, space-saving design. Increase the speed of your network server and backbone connections, or make Gigabit to the desktop a reality.Power users in the office, workgroup, or creative production environment can now move large, bandwidth-intensive files faster. Transfer graphics, CGI, CAD, or multimedia files across the network instantly. The versatile and compact 1RU height design of the DGS-1024D enables the device to be rackmounted in a standard 19 inch rack, while conserving valuable rack space.Power-PackedIt features a non-blocking switching architecture that filters and forwards packets at full wire-speed for maximum throughput. An 8K MAC address table provides scalability for even the largest networks. Address learning and aging, 802.3x Flow Control for full-duplex mode, and back pressure flow control for half-duplex mode alleviates traffic congestion and ensures reliable data transmission.Designed using industry standards, it is compatible with virtually all 10, 100, and 1000Mbps Ethernet devices and other vendor equipment. The D-Link DGS-1024D 10/100/1000 Mbps Gigabit Switch protects your existing network investments while providing you with a straightforward migration path to faster Gigabit speeds.Easy to useThe auto features of this gigabit switch make installation plug and play and hassle-free. No configuring is required. Auto MDI/MDI-X crossover on all ports eliminate the need for crossover cables or uplink ports. Auto-negotiation on each port senses the link speed of a network device (either 10, 100, or 1000 Mbps) and intelligently adjusts for compatibility and optimal performance.It also features diagnostic LEDs which display status and activity, allowing you to quickly detect and correct problems on the network. Every port also supports a cable diagnostic feature that helps to detect cable related problems.

D-Link DGS-108 Black Switches

- Plug and Play operation- 8 Gigabit Ethernet ports- Non-blocking architecture: simultaneous full speed on all ports- Fanless, silent operation to fit in any environment- Quality of Service (QoS) queues for traffic prioritisation- Solidly built with metal housing- Cable diagnostics function to detect faulty network cables- D-Link Green™ technology, saves energy and increases the product’s lifespanD-Link’s DGS-108 Gigabit Ethernet switch provides a cost-effective way for SOHO and SMB to create a small network and connect computers, wireless Access Points, IP cameras, network printers and other Ethernet devices quickly and easily without complicated configurations. This switch comes with 8 Gigabit Ethernet ports with an auto-sensing function to detect the maximum speed of the connected devices, allowing you to run your network with the best possible performance. Its fanless design makes the DGS-108 completely silent, ideal for offices, libraries or meeting rooms.Robust designThe DGS-108 is designed with durability and performance in mind. The sturdy metal housing will protect the switch against accidental harm, while helping to dissipate heat and to reduce stress on internal components. The visible LEDs allow for an easy reading of each port status and speed, helping to troubleshoot connectivity problems. For a convenient placement, the DGS-108 comes with a wall mounting kit and a slot for a Kensington security lock to protect it from theft.QoS (Quality of Service)Despite being an unmanaged, Plug and Play switch, the DGS-108 is able to classify network traffic by assessing the 802.1p field in the Ethernet frames, and forward them out of its ports depending on their priority. This allows for a smooth integration of video, voice and data traffic without delays or loss of quality.Cable diagnostics functionThe cable diagnostics function enables users to quickly troubleshoot faulty network cables that may lead to transmission errors. At startup, the switch performs a micro-test to assess the quality of the cables connected to its ports. If a fault is detected, the ambar LED will lit up. If the cables pass the test, the green LED will be illuminated, indicating that the network is error-free. This feature can save valuable time when trying to single out a faulty cable that causes problems in the whole network.Power-saving technologyThe DGS-108 is part of D-Link Green™, D-Link’s eco-friendly technology, providing energy savings, reduced power consumption, and a longer product lifespan without sacrificing operational performance or functionality. This switch implements the 802.3az Energy Efficient Ethernet (EEE) standard, which can save a substantial amount of energy by detecting the port status, putting them in low-power, stand-by mode when no network traffic is detected. Additionally, the Green Ethernet™ technology in the DGS-108 can detect the length of the network cables connected to its ports and provide only the right amount of energy required. This helps businesses to save money by reducing their electricity bills with no compromise on performance.
