3. Network Planning

3.1 Introduction to Switching

A network switch is one of the most important devices for today’s networking technology. It enables simultaneous transmission of multiple

packets, and it can partition a network more efficiently than bridges or routers. When performance bottlenecks are caused by congestion

at the network access point such as a file server, devices can be connected 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 can subdivide the network into smaller and more manageable segments, linking them to the larger network than can turn the hop

count back to zero, removing the limitation.

A switch can be easily configured in any Ethernet, Fast Ethernet, or Gigabit Ethernet network to significantly increase bandwidth while using

conventional cabling and network cards.

3.2 Application Examples

The PoE+ Gigabit Managed Switch Eco uses (8), (20), or (44) Gigabit Ethernet TP ports with Auto MDI-X and two slots for the

removable SFP module, which supports a number of types of fiber connections, including LC and BiDi-LC modules. It is not only designed to

segment your network, but also to provide a wide range of options in setting up network connections. Some typical applications showing the

10-Port PoE+ Gigabit Managed Switch Eco (LPB2810A) are described below.

NOTE: The LPB2826A and LPB2848A are similar to the LPB2810A, but have (20) or (44) Gigabit ports. The LPB2826A and LPB2848A also have

dual-media SFP/(10/100/1000) ports, which are described in the specifications section of this manual.
