[. . . ] 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. The switch also support multiple spanning trees which allow VLANs groups to maintain a more stable path between all VLAN members. This can reduce the overall amount of protocol traffic crossing the network, and provide a shorter reconfiguration time if any link in the spanning tree fails. Figure 2-5 Making VLAN Connections Note: When connecting to a switch that does not support IEEE 802. 1Q VLAN tags, use untagged ports. 2-6 APPLICATION NOTES Application Notes 1. 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. Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. Otherwise back pressure jamming signals may degrade overall performance for the segment attached to the hub. 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-LH: 70 km (43 miles) for single-mode fiber. 10GBASE-SR: 300 m (984 ft) for multimode fiber. 10GBASE-LR: 10 km (6. 2 miles) for single-mode fiber. 10GBASE-ER: 40 km (24. 9 miles) for single-mode fiber. However, power budget constraints must also be considered when calculating the maximum cable length for your specific environment. 2-7 NETWORK PLANNING 2-8 CHAPTER 3 INSTALLING THE SWITCH Selecting a Site TigerSwitch 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 50 °C (32 to 122 °F) and its humidity within 5% to 95%, 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. 44 m (8 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 switch 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, 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 1000, SMC8728L2 · Four adhesive foot pads · Bracket Mounting Kit containing two brackets and eight screws for attaching the brackets to the switch · Power Cord · 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 switch, 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 This switch can be mounted in a standard 19-inch equipment rack or on a desktop or shelf.
