Figure 2-1 Network Aggregation Plan 2-2 APPLICATION EXAMPLES Remote Connections with Fiber Cable Fiber optic technology allows for longer cabling than any other media type. A 10GBASE-SR (MMF) link can connect to a site up to 300 meters away, a 10GBASE-LR (SMF) link can connect to a remote site up to 10 km away and a 10GBASE-ER(SMF) link can connect to a site up to 40 km away. This allows a 10 Gigabit Ethernet Switch to serve as a collapsed backbone, providing direct connectivity for a widespread LAN. A 10GBASE-SR XFP transceiver can be used for a high-speed connection between floors in the same building, and a 10GBASE-LR XFP can be used for high-bandwidth core connections between buildings in a campus setting or to connect to a remote site. The figure below illustrates this switch connecting multiple segments with fiber cable.

Figure 2-2 Remote Connections with Fiber Cable 2-3 NETWORK PLANNING Making VLAN Connections This switch supports VLANs which 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. These switch also support multiple spanning trees which allow VLAN 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.

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, you can attach this switch to a router or WAN gateway. As a general rule the length of fiber optic cable for a single switched link should not exceed: · · · 10GBASE-SR: 300 m (984. 25 ft) for multimode fiber. 10GBASE-LR: 10 km (6. 21 miles) for single-mode fiber. 10GBASE-ER: 40 km (24. 85 miles) for single-mode fiber. However, power budget constraints must also be considered when calculating the maximum fiber optic cable length for your specific environment. 2-5 NETWORK PLANNING 2-6 CHAPTER 3 INSTALLING THE SWITCH Selecting a Site TigerSwitch 10G 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 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.
