[. . . ] When the time comes for further expansion, just connect to another hub or switch using one of the Gigabit Ethernet ports built into the front panel, or a Gigabit Ethernet port on a plug-in SFP transceiver. In the following figure, the 24-port switch is operating as a collapsed backbone for a small LAN. It is providing dedicated 10 Mbps full-duplex connections to 2-1 2 Network Planning workstations, 100 Mbps full-duplex connections to power users, and 1 Gbps full-duplex connections to servers. In addition, connected IP phones and wireless access points are receiving PoE power from the switch. . . . Servers 1 Gbps Full Duplex . . . Workstations 100 Mbps Full Duplex . . . Workstations 10 Mbps Full Duplex Power-over-Ethernet Devices 10/100 Mbps Full Duplex Figure 2-1 Collapsed Backbone Network Aggregation Plan With 24 parallel bridging ports (i. e. , 24 distinct collision domains), a Gigabit switch can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput. In the figure below, the 10/100/1000BASE-T ports are providing 1000 Mbps connectivity through cascaded switches. In addition, the switches are also connecting several servers at 1 Gbps.

Figure 2-2 Network Aggregation Plan 2-2 Application Examples 2 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 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. For long-haul connections, a 1000BASE-ZX SFP transceiver can be used to reach another site up to 100 kilometers away. The figure below illustrates three TigerSwitch 10/100/1000 units interconnecting multiple segments with fiber cable.

Figure 2-3 Remote Connections with Fiber Cable 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. 2-3 2 Network Planning R&D VLAN 1 Tagged Ports Untagged Ports VLAN unaware switch R&D Tagged Port VLAN aware switch Finance VLAN 2 Testing Marketing Finance Testing VLAN 3 VLAN 4 VLAN 3 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. 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. For network applications that require routing between dissimilar network types, you can attach these switches directly to a multi-protocol router. 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: 10 km (3. 1 miles) for single-mode fiber · 1000BASE-ZX: 80 km (62. 1 miles) for single-mode fiber However, power budget constraints must also be considered when calculating the maximum cable length for your specific environment. 2. 3. 2-4 Chapter 3: Installing the Switch Selecting a Site TigerSwitch 10/100/1000 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. [. . . ] · Sicherstellen, dass das Gerat an eine separate Stromquelle mit Erdanschlus mit einer Netzspannung von 100 bis 240 V AC (Wechselstromspannung), 50 bis 60 Hz, und innerhalb in einem Abstand von 2, 44 m (8 Fus) zu jedem Gerat installiert wird und on einem separaten Trennschalter bzw. Leistungsschalter mit Strom versorgt wird. Fur alle Gerate wird empfohlen, einen Filter oder einen Überspannungsschutz zu verwenden. Montage (Rack Mounting Instructions) Switch-Einheiten können an ein standardmäßiges 19-Zoll Einrichtungsrack, einen Arbeitstisch oder ein Regal montiert werden. Folgend finden Sie die Montageanweisungen für jeden Positionstyp. Rack-Montage Beachten Sie die folgenden Faktoren, bevor Sie die Rack-Montage beginnen: · Temperatur: Da die Temperatur innerhalb einer Rackeinheit höher als die D-1 D German Instructions Raumumgebungstemperatur sein kann, stellen Sie bitte sicher, dass die Rackumgebungstemperatur innerhalb des angegebenen Betriebstemperaturbereichs liegt.
