with any other segments (ports). This allows the total network capacity to be multiplied, while still maintaining
the same network cabling and adapter cards.
For Fast Ethernet or Gigabit Ethernet networks, a switch is an effective way of eliminating problems of chaining
hubs beyond the “two-repeater limit.” A switch can be used to split parts of the network into different collision
domains, for example, making it possible to expand your Fast Ethernet network beyond the 205-meter network
diameter limit for 100BASE-TX networks. Switches supporting both traditional 10Mbps Ethernet and 100Mbps
Fast Ethernet are also ideal for bridging between existing 10Mbps networks and new 100Mbps networks.
Switching LAN technology is a marked improvement over the previous generation of network bridges, which
were characterized by higher latencies. Routers have also been used to segment local area networks, but the cost
of a router and the setup and maintenance required make routers relatively impractical. Today’s Switches are an
ideal solution to most kinds of local area network congestion problems.
Switch Description
The DGS-108 Switch is equipped with eight ports providing dedicated 10, 100, or 1000 Mbps bandwidth. These
ports can be used for connecting PCs, printers, servers, routers, Switches, hubs, and other network devices. The
eight multi-speed ports use standard twisted pair cabling and are ideal for segmenting networks into small,
connected subnets. Each port can support up to 2000 Mbps of throughput in full-duplex mode. This stand-alone
Switch enables the network to use some of the most demanding multimedia and imaging applications
concurrently with other user applications without creating bottlenecks.
Features
The DGS-108 8-Port 10/100/1000BASE-T Gigabit Ethernet Switch was designed for easy installation and high
performance in an environment where traffic on the network and the number of users increase continuously.
