[. . . ] This allows you to assign multiple VLAN groups to the "trunk" ports (that is, tagged ports) connecting different switches.

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 Using Layer 3 Routing VLANs can significantly enhance network performance and security. However, if you use conventional routers to interconnect VLANs, you can lose most of your performance advantage. The Gigabit Ethernet Routing Switch provides wire-speed routing, which allows you to eliminate your conventional IP routers, except for a router to handle non-IP protocols and a gateway router linked to the WAN. The switch will continue to segregate Layer 2 traffic based on VLANs, but will now provide inter-VLAN connections for IP applications. This switch will perform IP routing for specified VLAN groups, a directly connected subnetwork, a remote IP subnetwork or host address, a subnetwork broadcast address, a switch IP address on a specific IP subnetwork, or an IP multicast address.

IP Routing for Unicast Traffic 2-6 CONNECTIVITY RULES Connectivity Rules When adding hubs (repeaters) to your network, please follow the connectivity rules listed below for these products. However, note that because switches break up the path for connected devices into separate collision domains, you should not include the switch or connected cabling in your calculations for cascade length involving other devices. 2-7 NETWORK PLANNING 1000 Mbps Gigabit Ethernet Collision Domain Maximum 1000BASE-T Gigabit Ethernet Cable Length Cable Type Category 5, 5e, or 6 100-ohm UTP or STP Maximum Cable Length 100 m (328 ft) Maximum 1000BASE-SX Gigabit Ethernet Cable Length Fiber Size 62. 5/125 micron multimode fiber 50/125 micron multimode fiber Fiber Bandwidth 160 MHz/km 200 MHz/km 400 MHz/km 500 MHz/km Maximum Cable Length 2-220 m (7-722 ft) 2-275 m (7-902 ft) 2-500 m (7-1641 ft) 2-550 m (7-1805 ft) Maximum 1000BASE-LX Gigabit Ethernet Cable Length Fiber Size 9/125 micron single-mode fiber Fiber Bandwidth N/A Maximum Cable Length 10 km (7 - 16404 ft) Maximum 1000BASE-ZX Fiber Optic Cable Distance Fiber Diameter 9/125 micron single-mode fiber (SMF) Fiber Bandwidth N/A Cable Length Range 70* - 100 km (43. 5 - 62. 1 miles) 100 Mbps Fast Ethernet Collision Domain Type 100BASE-T X Maximum Fast Ethernet Cable Distance Cable Type Max. Cable Length Category 5 or better 100-ohm UTP 100 m (328 ft. ) or STP 2-8 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. For network applications that require routing between dissimilar network types, you can attach this switch directly to a router. As a general rule the length of Gigabit fiber optic cable for a single switched link should not exceed 550 m (1805 ft) for 1000BASE-SX multimode fiber or 10km (16404 ft) for 1000BASE-LX single-mode fiber. However, power budget constraints must also be considered when calculating the maximum cable length for your specific environment. 2-9 NETWORK PLANNING 2-10 CHAPTER 3 INSTALLING THE SWITCH Selecting a Site TigerSwitch 1000 units can be mounted in a standard 19-inch equipment rack or on a flat surface. 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 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 or 100BASE-TX 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 and Category 5 or better for 100BASE-TX. 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. [. . . ] Collision A condition in which packets transmitted over the cable interfere with each other. CSMA/CD CSMA/CD (Carrier Sense Multiple Access/Collision Detect) is the communication method employed by Ethernet, Fast Ethernet, or Gigabit Ethernet. End Station A workstation, server, or other device that does not forward traffic. Ethernet A network communication system developed and standardized by DEC, Intel, and Xerox, using baseband transmission, CSMA/CD access, logical bus topology, and coaxial cable. [. . . ]
