Figure 2-2 Network Aggregation Plan 2-3 NETWORK PLANNING Remote Connections with Fiber Cable Fiber optic technology allows for longer cabling than any other media type. A 1000BASE-SX (MMF) link can connect to a site up to 550 meters away, a 1000BASE-LX (SMF) link up to 5 km, and a 1000BASE-ZX link up to 100 km. This allows a Gigabit Ethernet Switch 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, a 1000BASE-LX SFP can be used to connect to other buildings in a campus setting, and a 1000BASE-ZX SFP transceiver can be used for a long-haul connection to a remote site. The figure below illustrates this switch connecting multiple segments with fiber cable.

Figure 2-3 Remote Connections with Fiber Cable 2-4 APPLICATION EXAMPLES 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. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 Networks TigerSwitch10/100 6752A L 2 51/Down 52/Up 49 50 51 52 PWR Diag RPU 49 50 R&D VLAN 1 Tagged Ports Finance Untagged Ports VLAN unaware switch Marketing VLAN 2 Testing VLAN 3 VLAN 4 VLAN 3 Finance Tagged Port VLAN aware switch R&D Testing VLAN 1 VLAN 2 Figure 2-4 Making VLAN Connections Note: When connecting to a switch that does not support IEEE 802. 1Q VLAN tags, use untagged ports. 2-5 NETWORK PLANNING 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 singlemode fiber. 1000BASE-ZX: 100 km (62. 1 miles) for singlemode 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 Switch 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 10% 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. 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. [. . . ] The successor IEEE 802. 3 standard provides for integration into the OSI model and extends the physical layer and media with repeaters and implementations that operate on fiber, thin coax and twisted-pair cable. Fast Ethernet A 100 Mbps network communication system based on Ethernet and the CSMA/CD access method. Glossary-2 Gigabit Ethernet A 1000 Mbps network communication system based on Ethernet and the CSMA/CD access method. Full Duplex Transmission method that allows two network devices to transmit and receive concurrently, effectively doubling the bandwidth of that link.
