This device integrates 10 0Mbps Fast Et hernet and 10Mb ps Ethernet netwo rk capabilities in one high-performance, easy-to-use solution. Purpose This manual will familiarize you with the DES-105/108 and guide you through the in stallat ion process.
2 I NTRODUCTION Fast Ethernet Technology The growing im portance of LANs an d the i ncreasing complexity of desktop com puting appl ications a re fueling t he need for hi gh perform ance networks.
3 multiple segments is one of the most common ways of increasing available bandwidth. If segmented correctly, most network traffic will rem ain within a single segment, enjoying the fu ll-lin e speed bandwidth of that segment. Switches provide full-lin e speed an d dedicated bandwid th for all connections.
