3. Supports web based interface 4 Introduction Chapter 2 Network Planning Introduction to Switching A network switch allows simultaneous transmission of multiple packets via non crossbar switching This means that it can partition a network more efficiently than bridges or routers The switch has therefore been recognized as one of the most important building blocks for today s networking technology When performance bottlenecks are caused by congestion at the network access point such as the network card for a high volume file server the device experiencing congestion server power user or hub can be attached directly to a switched port And by using full duplex mode the bandwidth of the dedicated segment can be doubled to maximize throughput When networks are based on repeater hub technology the distance between end stations is limited by a maximum hop count However a switch turns the hop count back to zero So subdividing the network into smaller and more manageable segments and linking them to the larger network by means of a switch removes this limitation A switch can be easily configured in any Ethernet Fast Ethernet or Gigabit Ethernet network to significantly boost bandwidth while using conventional cabling and network cards 2 Network Planning Application Examples The switch is not only designed to segment your network but also to provide a wide range of options in setting up network connections
4. Application Notes 1 Full duplex operation only applies to point to point access such as when a switch is attached to a workstation server or another switch When the switch is connected to a hub both devices must operate in half duplex mode 2 For network applications that require routing between dissimilar network types you can attach the switch directly to a multi protocol router 3 As a general rule the length of fiber optic cable for a single switched link should not exceed 1000BASE SX 550 m 1805 ft for multimode fiber 1000BASE LX 5 km 3 1 miles for single mode fiber 1000BASE LH 70 km 43 miles for single mode fiber However power budget constraints must also be considered when calculating the maximum cable length for your specific environment 2 Network Planning 2 6 Chapter 3 Installing the Switch Selecting a Site switch units can be mounted in a standard 19 inch equipment rack or on a flat surface Be sure to follow the guidelines below when choosing a location The site should be atthe center of all the devices you want to link and near a power outlet be able to maintain its temperature within 0 to 45 C 32 to 113 F and its humidity within 10 to 90 non condensing provide adequate space approximately five centimeters or two inches on all sides for proper air flow beaccessible for installing cabling and maintaining the devices allow the status LEDs to be clearly visib
