[. . . ] In a basic stand-alone configuration, it can provide direct fullduplex connections for up to 10 workstations or servers. You can easily build on this basic configuration, adding direct full-duplex connections to workstations or servers. 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 figure below, the switch is operating as a collapsed backbone for a small LAN. It is providing dedicated 100 Mbps full-duplex connections to workstations and 1000 Mbps full-duplex connections to power users, and 1000 Mbps fullduplex connections to servers. Figure 7: Collapsed Backbone SMCGS10P-Smart Workstations 100 Mbps Full Duplex Workstations 1000 Mbps Full Duplex Servers 1000 Mbps Full Duplex POE CONNECTIONS The switch is an excellent choice for supplying power to connected PoE devices such as web cameras, IP telephones, or access points. The eight RJ-45 ports on the switch can provide up to 30 W of power to a connected device. The switch can supply 9. 37 W simultaneously to eight PoE devices among the eight Gigabit Ethernet ports, or 30 W simultanesously to two connected PoE devices. The total power cannot exceed the 75 W PoE power budget. ­ 31 ­ CHAPTER 2 | Network Planning Application Examples In the figure below, the switch is supplying power to three PoE devices. It is also providing dedicated 1000 Mbps full-duplex data connections to these devices. In addition, other non-PoE devices can be connected to the switch. Figure 8: Supplying PoE Power SMCGS10P-Smart Power-over-Ethernet Devices IP Telephone Access Point Web Camera NETWORK AGGREGATION PLAN With 10 parallel bridging ports (i. e. , 10 distinct collision domains), this 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 on the switch are providing 1000 Mbps connectivity for up to eight segments, while the 1000BASE-SFP ports are providing connectivity for two Gigabit segments.

Server Farm ­ 32 ­ CHAPTER 2 | Network Planning Application Examples 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 10 km, a 1000BASE-LH link up to 80 km, and a 100BASE-FX (SMF) link up to 20 km. This allows the switch to serve as a collapsed backbone, providing direct connectivity for a widespread LAN. The figure below illustrates the switch connecting multiple segments 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. 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. ­ 33 ­ CHAPTER 2 | Network Planning Application Notes Figure 11: Making VLAN Connections SMCGS10P-Smart R&D VLAN 1 Tagged Ports Untagged Ports VLAN unaware switch Tagged Port Finance VLAN 2 Testing R&D VLAN aware switch Marketing Finance Testing VLAN 3 VLAN 4 VLAN 3 VLAN 1 VLAN 2 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. 2. 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. 3. [. . . ] Cable Length 100 m (328 ft) Connector RJ-45 CABLE LABELING AND CONNECTION RECORDS When planning a network installation, it is essential to label the opposing ends of cables and to record where each cable is connected. Doing so will enable you to easily locate inter-connected devices, isolate faults and change your topology without need for unnecessary time consumption. To best manage the physical implementations of your network, follow these guidelines: Clearly label the opposing ends of each cable. Using your building's floor plans, draw a map of the location of all networkconnected equipment. [. . . ]
