1 A BOUT T HIS G UIDE Congratulations on your purchase of the DES-1024D 24-port 10/100Mbps Fast Ethernet Switch. This device integrates 100Mbps Fast Ethernet and 10Mbps Ethernet network capabilities into one highly flexible solution. Purpose This guide disc usses how to install your DE S-1024D.
2 I NTRODUCTION This chapter describe s the features of the DES-1024D and some background informati on about Ethernet/ Fast Ethernet s witching tec hnology. Fast Ethernet Technology Ethernet, along with its speedier coun terpart Fast Ethernet, is the most popular netw orking standa rd in use today.
3 Switching Technology Switching is a cost-effective way of i ncreasing the total network capacity available to users on a L AN. If an Et hernet netw ork begins t o display symptom s of congestio n, l.
4 Switching L AN technolo gy is a marked im provement ove r the pre vious generation of netw ork hubs and bridges, w hich were characteri zed by higher latencies. Rout ers have also been used to se gment local area netw orks, but the cost of a router, the setup and maint enance re quired, ma ke routers relatively impractical.
5 U NP ACKING AND S ETUP Unpacking Open the shippin g cartons of the DES-1024D and carefu lly unpack its contents. The carton should contain the following items: One DES-1024D 24-port 10/100Mbps F.
6 included with the device should be attached fir st, to minimize scratching or scarring of the surface on which th e Switch is place d. Attach these cushioning feet on the bottom at each corner of the device. Allow enough ventilation space b etween the device and the objects aro und it.
7 wiring closet wi th other equipm ent. Attach the mounting brackets on each side of the Switch’s front panel (as shown in the illustration below), and secure them with the screws provided.
