The DES-105/DES-108 Fast Ethernet Switches provide a quick, easy and economical way to add high speed networking to home offices, small and medium businesses. With data transfer speeds of up to 200 Mbps the DES-105/DES-108 are ideal for fast file transfers. They provide five or eight ports for easy expansion of your network for connecting printers,scanners,storage, and backup devices to any network. The DES-105/DES-108 are designed with durability and performance in mind. Their sturdy metal housing ensures the product can withstand extreme temperatures and can be placed in typical industrial environments such as factories, construction and mining. They help to dissipate heat and reduce stress on internal components. They are easy access, auto-sensing 10/100 front Ethernet ports with two LED indicators per port to quickly distinguish link status and speed. The DES-105/DES-108 switches also support Auto MDI/MDIX Crossover allowing each port to be plugged directly to a server, hub, router, or switch using regular straight-through twisted-pair Ethernet cables. Support for IEEE 802.1p QoS is included, which organises and prioritises time-sensitive and important data for efficient delivery. QoS prioritises network traffic so that time-sensitive data is delivered efficiently, even during bursts of high data traffic. This helps ensure an optimal experience for streaming media and VoIP calls. The DES-105/DES-108 are 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. These switches support IEEE 802.3az Energy Efficient Ethernet (EEE) standard which detects when a connected computer is shut down or when there is no Ethernet traffic, in which case the switches will proceed to power down the idle port, saving a substantial amount of power. This helps businesses to save money by reducing their electricity bills with no compromise on performance.
