24-port NWay Ethernet Switch User’s Guide ABOUT THIS GUIDE This User’s Guide tells you how to install your DES-3225G Series Switch, how to connect it to your Ethernet network, and how to set its configuration using either the built-in console interface or Web-based management. Terms For simplicity, this documentation uses the terms “Switch” (first letter upper case) to refer to the DES-3225G Series 24- port NWay Ethernet Switch, and “switch” (first letter lower case) to refer to all Ethernet swi

24-port NWay Ethernet Switch User’s Guide 1 INTRODUCTION This section describes the features of the Switch, as well as giving some background information about Ethernet/Fast Ethernet, Gigabit Ethernet, and switching technology. Fast Ethernet Technology The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high performance networks. A number of high-speed LAN technologies are proposed to provide greater bandwidth and improve client

24-port NWay Ethernet Switch User’s Guide Switching Technology Another key development pushing the limits of Ethernet technology is in the field 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 network capacity available to users on a local area network. A switch increases capacity and decreases network loading

24-port NWay Ethernet Switch User’s Guide Performance features ♦ Store and forward switching scheme capability to support rate adaptation and protocol conversion. ♦ Full- and half-duplex for both 10Mbps and 100Mbps connections. The 1000BASE-SX and 1000BASE-LX Gigabit Ethernet modules operate at full duplex only while the 1000BASE-T Gigabit Ethernet module can also operate in half-duplex mode when auto negotiate is selected. Full duplex allows the switch port to simultaneously transmit and receiv

24-port NWay Ethernet Switch User’s Guide Power on The DES-3225G switch can be used with AC power supply 100 - 240 VAC, 50/60 Hz. The Switch’s power supply will adjust to the local power source automatically and may be used without having any or all LAN segment cables connected. After the switch is plugged in, the LED indicators should respond as follows: ♦ All LED indicators will momentarily blink. This blinking of the LED indicators represents a reset of the system. ♦ The power LED indicator w
