[. . . ] A single switch can be easily configured to support several VLAN groups for various organizational entities (such as Finance and Marketing). When you expand port-based VLANs across several switches, you need to make a separate connection for each VLAN group. This approach is, however, inconsistent with the Spanning Tree Protocol, which can easily segregate ports that belong to the same VLAN. When VLANs cross separate switches, it is therefore better to use VLAN tagging. This allows you assign multiple VLAN groups to the trunk ports (that is, tagged ports) connecting different switches. Figure 2-2. Making VLAN Connections Note: When connecting to a switch that does not support IEEE 802. 1Q VLAN tags, use untagged ports. 2-3 NETWORK PLANNING Connectivity Rules When adding hubs (repeaters) to your network, please follow the connectivity rules listed below for Ethernet and Fast Ethernet. 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. 1000 Mbps Gigabit Ethernet Collision Domain Maximum Fiber Optic Cable Distance for 1000BASE-SX Fiber Size 62. 5/125 micron 50/125 micron 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 Fiber Optic Cable Distance for 1000BASE-LX Fiber Size 9/125 micron Fiber Bandwidth N/A Maximum Cable Length 2 m - 5 km (7 - 16404 ft) Maximum Cable Distance for 1000BASE-T Type Cat. 5, 5e 100-ohm UTP Connector RJ-45 Maximum Cable Length 100 m (328 ft) 2-4 NETWORK PLANNING 100 Mbps Fast Ethernet Collision Domain SMC 3-2 Rule for Class II Repeaters Between any two PCs or other stations in the same 100BASE-TX collision domain, there may be: · up to 3 link segments and · up to 2 Class II repeaters (hubs) SMC 2-1 Rule for Class I Repeaters Between any two PCs or other stations in the same 100BASE-TX collision domain, there may be: · up to 2 link segments and · up to 1 Class I repeater (hub) Maximum 100BASE-TX Network Diameter Using Repeaters Repeater Type and Number 1 Class I 1 Class II 2 Class II Twisted Pair 100BASE-TX 200 m (656 ft. ) 200 m (656 ft. ) 205 m (672. 4 ft. ) Maximum Fast Ethernet Cable Distance Cable Type Twisted Pair Fiber Connecting Any two devices Switch to switch, server or PC Half duplex Full duplex 412 m (1, 351. 4 ft. ) 2 km (1. 24 mi. ) Max.

This distinction between populated and unpopulated segments is significant for coax networks only. Maximum Cable Length Cable Type Twisted Pair, Categories 3, 4, 5 Thin Coax External Transceiver Drop Maximum Length 100 m (328 ft. ) 185 m (607 ft. ) 50 m (165 ft. ) 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. For network applications that actually require routing, such as when interconnecting dissimilar network types or distinct VLANs, you may have to attach the TigerSwtich 1000 directly to a router or Layer 3 switch. 2-6 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. Be sure to follow the guidelines below when choosing a location. N The site should: · · · · · N 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 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, transmitters, etc. Make sure that a separate grounded power outlet that provides 100 to 240 VAC, 50 to 60 Hz, is within 8 feet (2. 44 m) of each device and is powered from an independent circuit breaker. As with any equipment, using a filter or surge suppressor is recommended. N 3-1 INSTALLING THE SWITCH Equipment Checklist After unpacking the TigerSwitch 1000, 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.

Mounting instructions for each type of site follow. Rack Mounting Before rack mounting the switch, pay particular attention to the following factors: N 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 Appendix C) Mechanical Loading: Do not place any equipment on top of a rack-mounted unit Circuit Overloading: Be sure that the supply circuit to the rack assembly is not overloaded. Grounding: Rack-mounted equipment should be properly grounded. Particular attention should be given to supply connections other than direct connections to the mains. N N N To rack-mount devices: 1.
