Page 9: Introduction
Chapter 1 Introduction Congratulations on your purchase of the NETGEAR Model SW108 8-port Ethernet Switch. ™ The Model SW108 switch segments Ethernet networks to relieve bandwidth congestion instantly, without having to replace network wiring, interface cards, or software. This guide describes how to install and use the switch. It includes physical configuration guidelines for connecting multiple 10 megabit per second (Mbps) hubs and for connecting 10 Mbps Ethernet stations, PCs, and servers. -
Page 10: Types Of Ethernet Switches
Installation Guide for the Model SW108 Ethernet Switch This bandwidth improvement is accomplished very easily, with no change to the desktop (the network interface cards or software, and network wiring). As a result, the performance upgrade and the applications it enables are obtained very quickly and at a low cost. Types of Ethernet Switches Ethernet switches can be classified in different ways—as desktop switches or segment switches. -
Page 11: Features
Features The Model SW108 switch has the following key features: • Eight switched, 10 Mbps, Ethernet 10BASE-T ports • Full-duplex or half-duplex mode of operation Full-duplex mode doubles throughput of point-to-point connections by letting individual ports transmit and receive concurrently when the connecting device also supports full-duplex mode. -
Page 13: Physical Description
This chapter explains the hardware features of the NETGEAR Model SW108 Ethernet switch. It is divided into sections explaining the front and rear panels of the switch. Use the key at the bottom of each illustration to identify the panel components. -
Page 14: Ethernet Ports
Ethernet Ports The Model SW108 switch is equipped with eight 10 Mbps Ethernet ports that support one cable connection, unshielded twisted pair (UTP) cable. An eight-pin RJ-45 plug is used for connection to these ports. Each port uses vista RJ-45 connectors that have built-in LEDs, as illustrated in Figure 2-2. The LEDs, as described in Table 2-1, indicate that the connection to the port is valid and that the port is operating in full-duplex mode. -
Page 15: Table 2-1. Led Descriptions
LEDs You use LEDs on the Model SW108 switch to monitor and diagnose the devices. LEDs on the front panel of the switch and two LEDs on each port allow you to identify the following information: • Status of the switch power supply •... -
Page 16: Rear Panel
Rear Panel As illustrated in Figure 2-3, the rear panel has full-duplex (FDX), and half-duplex (HDX) toggle switches, a ground clip, and a standard AC power receptacle. Key: 1 = Ground clip 2 = FDX and HDX toggle switches to set the duplex mode of each 10 Mbps port 3 = AC power outlet Figure 2-3. -
Page 17: Applications
Applications This chapter presents an overview of the levels of service provided by incorporating the technology of the NETGEAR Model SW108 Ethernet switch into your network. The Model SW108 Ethernet switch is designed to provide flexibility in configuring your network connections. -
Page 18: Desktop Switching
Desktop Switching Figure 3-1 illustrates the Model SW108 switch used as a desktop switch to build a small network that enables users to have 10 Mbps access to a file server. Key: 1 = Server with 10 Mbps connection 2 = Model SW108 Ethernet switch (Normal/Uplink push button set to Normal position) 3 = PCs with 10 Mbps connection Figure 3-1. -
Page 19: Segment Switching
The Model SW108 switch can segment a network into multiple connected pieces, increasing overall bandwidth and throughput. Figure 3-2 illustrates the Model SW108 Ethernet switch segmenting networks that are built with the NETGEAR Model EN104 and Model EN108 Ethernet hubs. -
Page 21: Installation
Keep the carton, including the original packing materials. Use them to repack the switch if you need to return it for repair. To qualify for product updates and product warranty registrations, fill in the Warranty and Owner Registration Card within 30 days of purchase and return it to NETGEAR, Inc. Installation Chapter 4... -
Page 22: Installing The Switch On A Desktop
Installing the Switch on a Desktop Choose a location near the devices to be connected and close to an electrical outlet. Set the switch on a desktop or tabletop, allowing at least two inches (5 cm) of space on all sides to prevent restriction of airflow. -
Page 23: Verifying Installation
Set the FDX or HDX toggle switches on the rear panel for the selected duplex mode. A hub and repeater use a common collision domain for all communications and cannot support full-duplex mode. When connecting any of the 10 Mbps ports on the switch to a hub, set the port to HDX. -
