Switch (31) Hardware Installation and Connection (37) Hardware Overview (41) 29 30 CHAPTER This chapter introduces the main features and applications of the Switch. 1 Getting to Know Your Switch 1.1 Introduction This User's Guide covers the following models: ES-2108, ES-2108-F, ES-2108-LC, ES-2108G and ES-2108PWR. The following table lists features that are specific to the individual models. The other features discussed in this chapter are common to all of the models covered in this User's Guide. See Appendix A on page 249 for detailed features and standards support. Table 1 Model Specific Features MODEL FEATURE Dual personality interface: a 1000BASE-T copper RJ-45 port and a Small Form-Factor Pluggable (SFP) slot (also called a mini-GBIC slot), with one port active at a time Fast Ethernet SFP Slot Mini-GBIC Slot 100 Base-FX Fiber-Optic Port IEEE 802.3af Power over Ethernet compliant Ethernet Ports Fan-less design X X X X X X X X ES-2108 ES-2108-F ES-2108-LC ES-2108-G X ES-2108PWR X With its built-in web configurator, managing and configuring the Switch is easy. In addition, the Switch can also be managed via Telnet, SSH (Secure SHell), any terminal emulator program on the console port, or third-party SNMP management. 1.1.1 Backbone Application In this application, the Switch is an ideal solution for small networks where rapid growth can be expected in the near future. ES-2108 Series User's Guide 31 Chapter 1 Getting to Know Your Switch The Switch can be used standalone for a group of heavy traffic users. You can connect computers directly to the Switch's port or connect other switches to the Switch. In this example, all computers can share high-speed applications on the server. To expand the network, simply add more networking devices such as switches, routers, computers, print servers etc. Figure 1 Backbone Application 1.1.2 Bridging Example In this example application the Switch connects different company departments (RD and Sales) to the corporate backbone. It can alleviate bandwidth contention and eliminate server and network bottlenecks. All users that need high bandwidth can connect to high-speed department servers via the Switch. For ES-2108G, you can provide a super-fast uplink connection by using a Gigabit Ethernet/ mini-GBIC port on the Switch. Moreover, the Switch eases supervision and maintenance by allowing network managers to centralize multiple servers at a single location. Figure 2 Bridging Application 32 ES-2108 Series User's Guide Chapter 1 Getting to Know Your Switch 1.1.3 High Performance Switched Example The Switch is ideal for connecting two networks that need high bandwidth. In the following example, use trunking to connect these two networks. Switching to higher-speed LANs such as ATM (Asynchronous Transmission Mode) is not feasible for most people due to the expense of replacing all existing Ethernet cables and adapter cards, restructuring your network and complex maintenance. The Switch can provide the same bandwidth as ATM at much lower cost while still being able to use existing adapters and switches. Moreover, the current LAN structure can be retained as all ports can freely communicate with each other. Figure 3 High Performance Switched Application 1.1.4 IEEE 802.1Q VLAN Application Examples This section shows a workgroup and a shared server example using 802.1Q tagged VLANs. A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical networks. Stations on a logical network belong to one group. A station can belong to more than one group. With VLAN, a station cannot directly talk to or hear from stations that are not in the same group(s) unless such traffic first goes through a router. For more information on VLANs, refer to Chapter 8 on page 87. 1.1.4.1 Tag-based VLAN Example Ports in the same VLAN group share the same frame broadcast domain thus increase network performance through reduced broadcast traffic. VLAN groups can be modified at any time by adding, moving or changing ports without any re-cabling. ES-2108 Series User's Guide 33 Chapter 1 Getting to Know Your Switch Figure 4 Tag-based VLAN Application 1.1.4.2 VLAN Shared Server Example Shared resources such as a server can be used by all ports in the same VLAN as the server, as shown in the following example. In this example, only ports that need access to the server need belong to VLAN 1. Ports can belong to other VLAN groups too. Figure 5 Shared Server Using VLAN Example 1.2 Ways to Manage the Switch Use any of the following methods to manage the Switch. · Web Configurator. This is recommended for everyday management of the Switch using a (supported) web browser. See Chapter 4 on page 51. · Command Line Interface. Line commands offer an alternative to the Web Configurator and may be necessary to configure advanced features. See the CLI Reference Guide. · FTP. Use File Transfer Protocol for firmware upgrades and configuration backup/restore. See Section 26.8 on page 200. · SNMP. The device can be monitored and/or managed by an SNMP manager. See Section 27.3 on page 204. 34 ES-2108 Series User's Guide Chapter 1 Getting to Know Your Switch 1.3 Good Habits for Managing the Switch Do the following things regularly to make the Switch more secure and to manage the Switch more effectively. · Change the password. Use a password that's not easy to guess and that consists of different types of characters, such as numbers and letters. · Write down the password and put it in a safe place. · Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the Switch to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the Switch. You could simply restore your last configuration. ES-2108 Series User's Guide 35 Chapter 1 Getting to Know Your Switch 36 ES-2108 Series User's Guide CHAPTER This chapter shows you how to install and connect the Switch. 2 Hardware Installation and Connection 2.1 Freestanding Installation 1 Make sure the Switch is clean and dry. 2 Set the Switch on a smooth, level surface strong enough to support the weight of the Switch and the connected cables. Make sure there is a power outlet nearby. 3 Make sure there is enough clearance around the Switch to allow air circulation and the attachment of cables and the power cord. 4 Remove the adhesive backing from the rubber feet. 5 Attach the rubber feet to each corner on the bottom of the Switch. These rubber feet help protect the Switch from shock or vibration and ensure space between devices when stacking. Figure 6 Attaching Rubber Feet Do NOT block the ventilation holes. Leave space between devices when stacking. For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front and 3.4 inches (8 cm) at the back of the Switch. This is especially important for enclosed rack installations. ES-2108 Series User's Guide 37 Chapter 2 Hardware Installation and Connection 2.2 Mounting the Switch on a Rack This section lists the rack mounting requirements and precautions and describes the installation steps. Do NOT block the ventilation holes. Make sure that no objects obstruct the airflow of the fans. 2.2.1 Rack-mounted Installation Requirements · Two mounting brackets. · Eight M3 flat head screws and a #2 Phillips screwdriver. · Four M5 flat head screws and a #2 Phillips screwdriver. Failure to use the proper screws may damage the unit. 2.2.1.1 Precautions · Make sure the rack will safely support the combined weight of all the equipment it contains. · Make sure the position of the Switch does not make the rack unstable or top-heavy. Take all necessary precautions to anchor the rack securely before installing the unit. 2.2.2 Attaching the Mounting Brackets to the Switch 1 Position a mounting bracket on one side of the Switch, lining up the four screw holes on the bracket with the screw holes on the side of the Switch. Figure 7 Attaching the Mounting Brackets 2 Using a #2 Phillips screwdriver, install the M3 flat head screws through the mounting bracket holes into the Switch. 3 Repeat steps 1 and 2 to install the second mounting bracket on the other side of the Switch. 4 You may now mount the Switch on a rack.
