[. . . ] This allows a switch stack to serve as a collapsed backbone, providing direct connectivity for a widespread LAN. A 1000BASE-SX SFP transceiver can be used for a high-speed connection between floors in the same building, and a 1000BASE-LX transceiver can be used for high-bandwidth core connections between buildings in a campus setting. For long-haul connections, a 1000BASE-ZX SFP transceiver can be used to reach another site up to 100 kilometers away. The figure below illustrates three TigerSwitch 10/100/1000 switch stacks interconnecting multiple segments with fiber cable.

Figure 2-3 Remote Connections with Fiber Cable 2-4 APPLICATION EXAMPLES Making VLAN Connections The switch supports VLANs that can be used to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This provides a more secure and cleaner network environment. VLANs can be based on untagged port groups, or traffic can be explicitly tagged to identify the VLAN group to which it belongs. Untagged VLANs can be used for small networks attached to a single switch. However, tagged VLANs should be used for larger networks, and all the VLANs assigned to the inter-switch links.

Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a workstation, server or another switch). When the switch is connected to a hub, both devices must operate in half-duplex mode. For network applications that require routing between dissimilar network types, you can attach the switch directly to a multi-protocol router. As a general rule, the length of fiber optic cable for a single switched link should not exceed: · 1000BASE-SX: 550 m (1805 ft) for multimode fiber · 1000BASE-LX: 5 km (3. 1 miles) for single-mode fiber · 1000BASE-ZX: 100 km (62. 1 miles) for single-mode fiber However, power budget constraints must also be considered when calculating the maximum cable length for your specific environment. 2-6 CHAPTER 3 INSTALLING THE SWITCH Selecting a Site TigerSwitch 10/100/1000 units can be mounted in a standard 19-inch equipment rack or on a flat surface. Be sure to follow the guidelines below when choosing a location. · The site should: - be at the center of all the devices you want to link and near a power outlet. - be able to maintain its temperature within 0 to 40 °C (32 to 104 °F) and its humidity within 10% to 90%, non-condensing - provide adequate space (approximately five centimeters or two inches) on all sides for proper air flow - be accessible for installing, cabling and maintaining the devices - allow the status LEDs to be clearly visible · Make sure twisted-pair cable is always routed away from power lines, fluorescent lighting fixtures and other sources of electrical interference, such as radios and transmitters. · Make sure that the unit is connected to a separate grounded power outlet that provides 100 to 240 VAC, 50 to 60 Hz, is within 2 m (6. 6 feet) of each device and is powered from an independent circuit breaker. As with any equipment, using a filter or surge suppressor is recommended. 3-1 INSTALLING THE SWITCH Ethernet Cabling To ensure proper operation when installing the switches into a network, make sure that the current cables are suitable for 10BASE-T, 100BASE-TX or 1000BASE-T operation. Check the following criteria against the current installation of your network: · Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP) cables with RJ-45 connectors; Category 3 or better for 10BASE-T, Category 5 or better for 100BASE-TX, and Category 5, 5e or 6 for 1000BASE-T. · Protection from radio frequency interference emissions · Electrical surge suppression · Separation of electrical wires (switch related or other) and electromagnetic fields from data based network wiring · Safe connections with no damaged cables, connectors or shields RJ-45 Connector Figure 3-1 RJ-45 Connections 3-2 EQUIPMENT CHECKLIST Equipment Checklist After unpacking the TigerSwitch 10/100/1000 unit, check the contents to be sure you have received all the components. Then, before beginning the installation, be sure you have all other necessary installation equipment. Package Contents · TigerSwitch 10/100/1000 unit, SMC8024L2 · Four adhesive foot pads · Bracket Mounting Kit containing two brackets and eight screws for attaching the brackets to the switch · Power cord--either US, Continental Europe or UK · RS-232 console cable · This Installation Guide · Installation and Management Guide CD · SMC Warranty Registration Card--be sure to complete and return to SMC Optional Rack-Mounting Equipment If you plan to rack-mount the switches, be sure to have the following equipment available: · Four mounting screws for each device you plan to install in a rack--these are not included · A screwdriver (Phillips or flathead, depending on the type of screws used) 3-3 INSTALLING THE SWITCH Mounting A TigerSwitch 10/100/1000 unit can be mounted in a standard 19-inch equipment rack or on a desktop or shelf. Mounting instructions for each type of site follow. Rack Mounting Before rack mounting the switch, pay particular attention to the following factors: · Temperature: Since the temperature within a rack assembly may be higher than the ambient room temperature, check that the rack-environment temperature is within the specified operating temperature range (see page C-2).
