1 A BOUT T HIS M ANUAL Congratulations on your purchase of the DES - 1526. This Switch integrates 100Mbps Fast Ethernet and 10Mbps Ethernet network capabilities in a highly flexible package. Since this S witch ’ s Port - 1 to Port - 24 are Power over Ethernet (PoE) ports, it will automatically detect the presence of IEEE 802.3af - compliant devic[...]

2 I NTRODUCTION This chapter describes the features of the DES - 1526 a nd some background information about Fast Ethernet , Gigabit Ethernet, S witch ing, VLAN , and Power over Ethernet technologies. Fast Ethernet Technology The growing importance of LANs and the increasing complexity of desktop comp uting applications are fueling the need for hig[...]

3 Gigabi t Ethernet Technology Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for CSMA/CD protocol, full - duplex, flow control, and management objects, but with a tenfold increase in theoretical throu ghput over 100Mbps Fast Ethernet and a one hundred - fold increase over 10Mbps Eth[...]

4 Switching Technology Another approach to pushing beyond the limits of Ethernet technology is the development of switching technology. A switch bridges Ethernet packets at the MAC address level of the Ethernet protocol transmitting among connected Ethernet or Fast Ethernet LAN segments. Switching is a cost - effective way of increasing the total n[...]

5 VLAN (Virtual Local Area Network) A VLAN is a group of end - stations that are not constrained by their physical location and can communicate as if a common broadcast do main, a LAN. The primary utility of using VLAN is to reduce latency and the need for routers, using faster switching instead. Other VLAN utility includes : u Security : Security [...]

6 Power over Ethernet (PoE) Power over Ethernet (PoE) integrates power and data onto one single cabling inf rastructure, eliminating the need to have AC power available at all locations. Power and Data are integrated onto the same cable. Supporting c ategory 5/5e up to 100 Meters , PoE will provide power to PoE compatible device s , s uch as IP tel[...]
