Page 28: Chapter 5 Network Configuration Examples
This chapter provides an overview of Ethernet technology and the levels of service that are provided by incorporating NETGEAR Ethernet hubs and switches into your network. Examples are given to illustrate the function of the hubs and switches in several configurations that provide those different levels of service to network users. -
Page 29: Configuration Examples
− Multiport switch with Fast Ethernet backbone 100BASE-TX Shared Repeater In this configuration, the Model FE508 and Model FE516 hubs are used in a pure 100 Mbps network. The Model FE508 and Model FE516 hubs can be used in a standalone network with users attached directly to the hub, as shown in Figure 5-1. -

10 Mbps link, congestion and collisions occur more frequently, resulting in less data throughput. Adding a Model FE508 or Model FE516 hub allows power users (for example, those using CAD applications) to be grouped together in the 100 Mbps Fast Ethernet network, isolated from the 10 Mbps network users who need occasional server access. - Page 31 Installation Guide for the Model FE508 and FE516 Fast Ethernet Hubs Figure 5-2 illustrates 100 Mbps users connected to a Model FE516 hub accessing a common server, integrated with the NETGEAR Model SW502 Ethernet Switch and a Model EN516 Ethernet Hub to form a mixed speed network.

Page 40: Patch Panels And Cables
Installation Guide for the Model FE508 and Model FE516 Fast Ethernet Hubs Patch Panels and Cables If you are using patch panels, be sure that they meet the 100BASE-T requirements. NETGEAR recommends Category 5 for all patch cables and work area cables to ensure your UTP patch cable rating meets or exceeds the distribution cable rating. - Page 41 Installation Guide for the Model FE508 and Model FE516 Fast Ethernet Hubs The NEXT loss between two particular pairs within a cable is a function of the twist per unit length for each pair. The higher the twist rate, the higher the NEXT loss value and the lower the NEXT noise.
