Chapter 2 Network Configuration The BayStack 70 Series 10/100 Ethernet Switch is designed to provide flexibility in configuring your network connections. Each switch in the series can be used as a standalone device or can be used with 10 Mb/s and/or 100 Mb/s hubs or other interconnection devices in various configurations. The configuration examples in this chapter illustrate the integration of the switches in network environments of all sizes and types.
Installation and Reference for the BayStack 70 Series 10/100 Ethernet Switches Types of Ethernet Switches Ethernet switches can be classified as desktop switches or as segment switches. A desktop switch is designed to support one or a few PCs per port. It is generally used when individuals need the full 10 Mb/s network throughput to support their applications.
Network Configuration Desktop Switching Figure 2-1 illustrates a BayStack 70-8T 10/100 Ethernet Switch used as a desktop switch to rebuild a small network that enables users to have 100 Mb/s access to a file server or network center. You can use the BayStack 70-16T 10/100 Ethernet Switch or BayStack 70-24T 10/100 Ethernet Switch as a desktop switch, in a similar application, if you have more users or devices to connect.
Installation and Reference for the BayStack 70 Series 10/100 Ethernet Switches Segment Switching The BayStack 70 Series 10/100 Ethernet Switch can segment a network into multiple connected pieces, increasing overall bandwidth and throughput. Figure 2-2 illustrates a BayStack 70-24T 10/100 Ethernet Switch segmenting networks that are built with BayStack 60-24T Ethernet Hubs.

Installation and Reference for the BayStack 70 Series 10/100 Ethernet Switches Extending a Network Ethernet specifications limit the length of cable between hubs and PCs to 100 meters (m) for a total diameter of 200 m. By adding Fast Ethernet switches between hubs, the network is expanded by 200 m with the addition of each switch. Figure 2-3 illustrates a network of BayStack 70-8T 10/100 Ethernet Switches integrated with three BayStack 70-24T 10/100 Ethernet Switches.
Network Configuration Bridging from 10BASE-T to 100BASE-TX Networks The BayStack 70 Series 10/100 Ethernet Switch can function as a two-port bridge connecting traditional 10BASE-T Ethernet networks to 100BASE-TX Fast Ethernet networks. Users requiring increased network bandwidth can be upgraded to 100 Mb/s while remaining connected to the rest of the network.
Installation and Reference for the BayStack 70 Series 10/100 Ethernet Switches Power Workgroups The BayStack 70 Series 10/100 Ethernet Switch increases bandwidth for power, or high-density, workgroups and strengthens network throughput. As shown in Figure 2-5, a BayStack 70-24T 10/100 Ethernet Switch connects to several BayStack switches, as well as high-density end stations and servers.

Installation and Reference for the BayStack 70 Series 10/100 Ethernet Switches • Optional, country-specific power cord, which can be purchased with your switch • Warranty card • Safety Information card Operating Environment Before you begin installing your switch, prepare the installation site. Make sure the operating environment, as listed in Appendix A, “Technical Specifications,” meets the physical requirements of the switch.
Installation Installing the Switch Before installing the switch: 1. Unpack the switch. 2. Choose a location near the devices to be connected and close to an electrical outlet. 3. Proceed to “Installing the BayStack 70 Series 10/100 Ethernet Switch on a Flat Surface” or “Mounting the BayStack 70-24T 10/100 Ethernet Switch in a Rack.
Installation and Reference for the BayStack 70 Series 10/100 Ethernet Switches 3. Attach any additional devices to the ports in your switch. For instructions to connect to additional switches or other devices, refer to “Connecting Devices to the Switch” on page 3-5. Mounting the BayStack 70-24T 10/100 Ethernet Switch in a Rack The BayStack 70-24T 10/100 Ethernet Switch occupies a 1.6 unit (1.6u) rack space and can be installed in most standard 19-inch equipment racks.
Installation 3. Using a #1 Phillips screwdriver, tighten the screws to secure each bracket. 4. Hold the switch with the mounting holes in the brackets aligned with the holes in the rack. 5. Insert two screws, appropriate for your 19-inch rack, into each of the mounting brackets and tighten the screws. 70-2 4T Swit ch 9350FA Figure 3-1.
Installation and Reference for the BayStack 70 Series 10/100 Ethernet Switches You can connect to another device through any of the ports on the switch. The MDI/MDI-X button eliminates the need to use a crossover twisted pair cable when connecting similarly wired devices.
Installation To connect power to the switch: 1. Connect the power adapter or power cord to the switch using one of the following methods: — For the BayStack 70-8T 10/100 Ethernet Switch or BayStack 70-16T 10/ 100 Ethernet Switch, connect the DC power adapter to the power adapter receptacle on the rear panel of the switch. Then connect a standard power cord to the adapter. Warning: Use only the power adapter that was shipped with your switch to supply power to that switch.
Installation and Reference for the BayStack 70 Series 10/100 Ethernet Switches Checking the Diagnostic Displays Figure 3-2 illustrates the LED indicators on theBayStack 70-24T 10/100 Ethernet Switch. LEDs on the BayStack 70-8T 10/100 Ethernet Switch and BayStack 70-16T 10/100 Ethernet Switch are identical, although there are only as many LEDs as are required for the ports on each model.
Installation Table 3-1 describes the LEDs that monitor the BayStack 70 Series 10/100 Ethernet Switch. Table 3-1. Description of Switch and Port Status LEDs Type Label Color Activity Description Port Status 10/100 Link/Activity Yellow On Port is connected at 10 Mb/s. Yellow Blinking 10 Mb/s activity is occurring on the port. Green On Port is connected at 100 Mb/s. Blinking 100 Mb/s activity is occurring on the port. Off No link is established on the port.
Chapter 4 Troubleshooting This chapter provides methods for diagnosing problems with the BayStack 70 Series 10/100 Ethernet Switch. Using the LED Display Use the LED display to help you identify the type of problem you have; then check the following: • Verify that the switch is powered on. • Verify that each cable and port connection has the correct pin assignment and no connections are loose. • A good link on a port is verified when the Link/Activity LED is lit for that port.
