Introduction
 
Congratulations on your purchase of the NETGEAR
 
 
 Model FS516 16-Port Fast Ethernet Switch. 
The switch provides you with a low-cost, high-performance network solution and is designed to 
support power workgroups operating at either 10 megabits per second (Mbps) or 100 Mbps.
This guide describes how to install and use the switch. It includes physical configuration 
guidelines for connecting multiple 10 or 100 Mbps hubs and for connecting 10 or 100 Mbps 
Fast Ethernet stations, PCs, and servers.
 
Benefits of Using Switching Technology
 
A majority of installed networks today are based on shared network technology. With this 
technology, a number of users or groups of users share a total available network bandwidth (or 
network capacity) of 10 Mbps, 100 Mbps, or other amounts of network bandwidth. For example, 
with a total of 10 users, the average bandwidth available to each user on a 10 Mbps network is 
calculated as 10/10 Mbps, which equals 1 Mbps of bandwidth per user. On a 100 Mbps (Fast 
Ethernet) network, the average bandwidth available to each of the 10 users is 100/10 Mbps, which 
equals 10 Mbps of bandwidth per user.
Ethernet switches significantly increase network throughput by segmenting network traffic. They 
check traffic coming in to each port to learn which network device is located on which segment. 
Based on this information, switches forward cross-segment traffic only to the appropriate segment. 
The traffic will not show up in the other segments because it is filtered out. In this way, network 
capacity is fully reserved for traffic destined for that segment only, and other segments will not 
be saturated with unnecessary traffic.
Ethernet switches provide private, dedicated, 10 Mbps (or 100 Mbps) capacity to each connected 
PC/server or hub/workgroup segment, which is significantly higher than in a shared environment. 
The higher bandwidth enables the use of applications such as multimedia, imaging, video, or high- 
performance client-server functions among users who are spread out over the network.
